Conclusion of the contract 1.1.1. The contract for the use of sipgate services is concluded when sipgate accepts the customer’s order for the provision of the services. Acceptance is deemed to have been declared by sipgate ten calendar days after receipt of the customer’s order, provided that the sipgate connection and the sipgate account have been activated and enabled by that time. The customer is bound to their application for 5 working days. 1.1.2. The details regarding the contract term are primarily set out in the sipgate service description. If nothing else is specified there, the contract has no minimum term. #### 1.2. Ordinary termination 1.2.1. The details regarding the notice period are primarily set out in the sipgate service description. If nothing else is specified there, the contract may be terminated by either party with one calendar day’s notice to the end of the month. 1.2.2. Terminations must be made by email or in writing (letter or fax). #### 1.3. Extraordinary termination 1.3.1. sipgate reserves the right to extraordinary termination for good cause. Good cause exists in particular if the customer culpably breaches their obligations under the contractual relationship and it is unreasonable for sipgate to wait until the end of the notice period. Such a case exists, among others, if the customer: * creates a sipgate account under a false name or false identity and/or * uses the sipgate account, the connection, or the assigned telephone number in an abusive manner and/or * if insolvency proceedings are opened against the customer’s assets or the customer files an application for the opening of insolvency proceedings and/or * chargebacks occur after direct debits. 1.3.2. In addition, sipgate shall have a right of extraordinary termination in the event of changes to the legal basis of this contract, or orders and/or directives relating to the contract issued by authorities, courts, or other holders of public authority, provided that these make continued adherence to the contract unreasonable for sipgate. 1.3.3. The customer’s statutory right to extraordinary termination for good cause remains unaffected. #### 1.4. sipgate credit upon termination of the contract 1.4.1. If the customer has credit in their sipgate account at the time the termination takes effect, sipgate undertakes to refund this to the customer upon corresponding request. The customer can submit the request via their sipgate account. The refund by sipgate shall be made by way of a credit to the customer’s specified bank or credit card account. 1.4.2. Any other refund of the sipgate credit is excluded. #### 1.5. Inactive accounts If the customer has a sipgate account that they have not used for more than one year (inactive account), sipgate is entitled to delete the sipgate account. sipgate will first inform the customer of the intended deletion via the email address stored in the sipgate account. If the customer does not object within 4 weeks, sipgate will delete the customer’s sipgate account. ### 2. Customer’s duties to cooperate 2.1. The customer is responsible for maintaining an Internet access suitable for use with sipgate (see requirements for use – Internet access). If this is not the case, the mutual performance obligations arising from the contractual relationship remain unaffected. 2.2. The customer must take all necessary and customary protective measures against unauthorized and abusive use of their sipgate connection by third parties. If the customer becomes aware of unauthorized or abusive use, they must inform sipgate immediately. 2.3. sipgate processes essential communication processes (including those relevant to the contract) via email. The customer undertakes to provide a valid email address of their own when registering with sipgate and to check it regularly, as well as to inform sipgate without delay of any changes to their email address. 2.4. If changes occur that affect the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed of these without delay. This duty to notify applies in particular to the following points: * Change of the customer’s place of residence/company headquarters (among other things necessary for the correct localization of emergency calls). Further information at: [Notes on placing emergency calls](http://www.sipgate.de/team/nutzungsbedingungen#emergency_call) * Change of the customer’s email address * for payments using the Autoprepay method, bank account details and credit card information. 2.5. The customer may use the connections to sipgate only as intended and in accordance with the (telecommunications) laws and regulations in their respectively valid version. The customer is obliged not to misuse the telecommunications services offered by sipgate for purposes that contravene statutory provisions, the relevant [sipgate service description](https://www.sipgate.de/leistungsbeschreibung) or the sipgate GTC. 2.6. The customer undertakes not to use any equipment or run any applications that may lead to changes in the physical or logical structure of the network made available by sipgate. 2.7. The customer undertakes to keep access data to their sipgate account and user accounts, as well as access data for sipgate’s VoIP service (user password or SIP ID and SIP password), confidential and secure, and not to disclose them to third parties. If the customer has lawfully disclosed access data to third parties (e.g. their employees), they must inform them of the obligation to keep the access data confidential and secure and require them accordingly. Private customers on tariffs with multiple users (upgrade to business S, L, XL) may only pass on the contractual services to members of their own household. 2.8. The customer agrees that their telephone number may, if necessary, be transferred to a network operator other than the one used at the time the contract was concluded. This entails no costs or disadvantages for the customer, and the contract between sipgate and the customer is not affected thereby. 2.9. sipgate is entitled to change the customer’s telephone numbers * if the customer agrees to the change, * if this is required due to legal provisions or official measures (in particular the Telecommunications Numbering Ordinance or decisions of the Federal Network Agency), * or if there are corresponding economic or legal constraints that sipgate cannot resolve otherwise with reasonable effort. 2.10. The customer is not permitted to pass on sipgate services rendered to them to third parties in a commercial manner without sipgate’s consent. 2.11. If there is misuse by the customer or a user authorized by them (e.g. breaches of 2.5., 2.6., 2.10. or comparable breaches) and the customer does not cease the misuse within a reasonable period despite being requested to do so by sipgate, sipgate is entitled to block the customer’s sipgate connection or – where applicable – delete user accounts created by the customer. To the extent that the customer is responsible for the blocking or deletion, sipgate will charge the customer for the costs of blocking/deletion. The customer is obliged to pay the basic fees incurred during a blocking period if they are responsible for the blocking. ### 3. Connection charges 3.1. The customer is obliged to pay for any use of their connection for which they are responsible. 3.2. The customer is also obliged to pay the charges incurred by the user or co-user. This also applies in the event of abusive use, unless the customer proves that they are not at fault for any breach of duty. 3.3. The obligation to pay remuneration does not apply if facts justify the assumption that third parties have influenced the charged connection fee by unauthorized changes to public telecommunications networks. 3.4. The charges for the VoIP service are determined by the price list applicable at the start of each individual connection for the product selected by the customer according to the sipgate service description. The current price list can be viewed online at any time via the valid link. ### 4. Billing and payment #### 4.1. Billing methods sipgate distinguishes between three different billing methods: Prepay, Autoprepay and Postpay. 4.1.1. Prepay method: in this procedure, the customer first pays an amount of their choosing to sipgate (sipgate credit) and can only use chargeable sipgate products after payment has been received, in accordance with their sipgate credit. Possible payment methods are bank transfer, direct debit and credit card. Unused sipgate credit does not expire. 4.1.2. Autoprepay method: Autoprepay is identical to the Prepay method, except that the customer’s sipgate credit is automatically topped up again when it falls below a minimum amount set by the customer. Possible payment methods for Autoprepay are direct debit and credit card. Unused sipgate credit does not expire. 4.1.3. Postpay method: sipgate reserves the right to offer the customer the option of paying only after service provision by sipgate on the basis of a corresponding invoice. 4.1.4. If the service description for the contract booked by the customer provides for the Autoprepay method as the billing method, the customer must ensure that their current bank account details or credit card details are stored in their sipgate account. If this is not the case, or if the customer revokes the direct debit authorization or authorization to charge the credit card, a negative credit balance (a claim by sipgate against the customer) may arise as a result of telephone calls or monthly fees. In this case, sipgate is entitled to request by email that the customer settle their negative credit balance. #### 4.2. Payment methods 4.2.1. In addition to bank transfers, sipgate also offers direct debit and credit card payments, provided the customer gives consent for this. However, participation in the Autoprepay method is only possible if the customer consents to recurring direct debit or credit card payments. The customer must declare this consent when activating the Autoprepay billing method in their account or in writing or by email to sipgate. If charging the selected payment method is unsuccessful, sipgate is entitled to use alternative payment methods stored in the account. 4.2.2. The pre-notification period for SEPA direct debits is one day. 4.2.3. For returned direct debits or collections, the customer must reimburse the costs incurred insofar as they are responsible for them. sipgate will charge the customer for the costs incurred in connection with the rejection (third-party fees of the customer’s bank as well as fees of sipgate’s bank) and will collect them from the account balance, unless the customer proves that no damage at all, or damage to a significantly lesser extent, occurred. 4.2.4. If, in exceptional cases, the customer pays by another means, for example in the event of late payment due to a returned direct debit or insufficient funds, payment discharges the debt only if the customer has sufficiently specified the purpose of use (in particular the invoice number or a comparable, unambiguous booking code from sipgate) when making the payment. This applies accordingly to payments by third parties. 4.2.5. sipgate reserves the right to offer the customer additional payment methods (e.g. PayPal) in addition to direct debit or credit card payments. #### 4.3. Form of the invoice 4.3.1. sipgate issues invoices exclusively as PDF files by email or for download. It is not possible to issue an invoice in paper form. 4.3.2. The customer agrees to have their invoice sent by email and is informed that confidential data transmission over the internet cannot be guaranteed. For this reason, sipgate invoices do not contain itemized billing records. These can be obtained separately by the customer. 4.3.3. The mandatory invoice details (§ 14(4) UStG) are included in the invoice based on the information provided by the customer in their sipgate account. The customer is obliged to keep this information up to date. sipgate is not obliged to create invoices that deviate from this information. #### 4.4. Due date and default 4.4.1. Claims for ongoing contracts that arise at monthly intervals (or at other regular intervals) are due on the 1st day of each month (or period), unless the service description provides otherwise. To the extent that claims do not arise at regular intervals, they become due upon receipt of the invoice by the customer. 4.4.2. The statutory provisions apply to default. 4.4.3. If the customer is in default, sipgate is entitled to block the service in accordance with § 61 (3) et seq. TKG. 4.4.4. If the customer is a consumer (within the meaning of § 13 BGB) and is in default, interest will be charged at five percentage points above the respective base interest rate of the European Central Bank. If the customer is an entrepreneur (within the meaning of § 14 BGB), eight percentage points above the base interest rate will be charged. sipgate reserves the right to assert further claims arising from late payment (e.g. reminder fees). 4.4.5. After eight weeks from receipt of the invoice, sipgate is entitled to delete the connection data underlying the invoice, which is why subsequent objections can no longer be taken into account. This applies accordingly if the customer requests premature deletion of the connection data from sipgate. A complete review of the invoice is therefore only possible as long as the customer’s connection data are fully stored. 4.4.6. The customer may only offset claims of sipgate GmbH against claims that have been legally established or are undisputed. #### 4.5. Objections 4.5.1. The customer must carefully check sipgate’s invoices. Any objections to the amount of the invoice must be raised in writing by the customer no later than eight weeks after receipt of the invoice. If the customer has credit with sipgate with which sipgate offsets basic fees and telephone charges, objections to the offsetting must, contrary to sentence 1, be raised no later than eight weeks after the end of the month in which the charges arose. The amount of the offsetting amounts can be found in the itemized billing record. The due date of the invoice amount is not affected by the raising of objections. 4.5.2. Objections to the invoice or to the offsetting against credit are excluded insofar as the relevant traffic data have been deleted within the statutory periods (eight weeks) or at the customer’s express request before the objections were raised. 4.5.3. If objections are not raised within the period of eight weeks under no. 4.5.1, the invoice/offsetting against credit is deemed approved by the customer. sipgate points out this legal consequence in the invoices. 4.5.4. In the event of justified objections raised in good time, any overpayment shall first be offset against outstanding payment claims of sipgate. If no outstanding payment claims exist, a credit note shall be issued. ### 5. Data protection 5.1. The legal basis for handling the customer’s personal data includes, among others, the General Data Protection Regulation (GDPR), the Federal Data Protection Act (BDSG), the Telecommunications Act (TKG), and the Telecommunications and Telemedia Data Protection Act (TTDSG). Personal data are collected, processed, or used only if the data subject has consented or if the TTDSG or another legal provision requires or permits it. 5.2. Data processing is therefore in particular permitted insofar as it is necessary. This is necessary for the establishment and design of the contractual relationship (inventory data), for the provision of telecommunications services (connection data), and for their billing (billing data). 5.3. sipgate observes telecommunications secrecy in accordance with the statutory requirements. 5.4. Detailed information on how sipgate handles personal data can be found in our [privacy policy](http://www.sipgate.de/team/datenschutz), which also forms part of the sipgate GTC. 5.5. The customer instructs sipgate to maintain a monthly itemized billing record, which they can access via the administrator account. This record lists all chargeable connections individually, including, among other things, the date, destination number, start and duration of the connection, and the charge for the individual connection. The numbers of the connections are shown, according to the customer’s choice, either shortened by the last three digits or in full length. The customer may also completely deactivate the itemized billing record in their administrator account. If the customer does not exercise their right of choice, the entries will be shown without shortening. The customer undertakes to inform all current and future co-users of their sipgate account, or in the case of business use all current and future employees, without delay and to comply with the co-determination provisions. 5.6. The customer instructs sipgate to store the general data (time, duration) of telephone calls, faxes, and SMS messages incoming to or outgoing from sipgate, independently of the itemized billing record, for the call list/event list and to make it available to the respective user on their user interface. 5.7. sipgate deletes customer data insofar as the customer issues a corresponding request, but only insofar as this is permitted under the TKG or other legal provisions. If objections have been raised, sipgate is entitled to retain the traffic data until the objections have been finally clarified. ### 6. Liability 6.1. For financial losses, sipgate is liable up to a maximum amount of €12,500.00 per customer. Towards the totality of customers, liability is limited to €30 million per single act or single damaging event. If the amounts payable to several customers on the basis of the same event exceed the maximum limit, compensation shall be reduced in proportion to the ratio of the total amount of compensation claims to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally. 6.2. Liability for consequential costs arising from emergency calls outside the specified place of residence or company headquarters is excluded. 6.3. Otherwise, sipgate is liable only for gross negligence or intent, unless this concerns the breach of an essential contractual obligation (so-called cardinal obligation). In the event of a slightly negligent breach of a cardinal obligation, liability is limited to such contract-typical damages as were reasonably foreseeable at the time the contract was concluded. 6.4. sipgate’s liability for warranted characteristics as well as under the provisions of the Product Liability Act and for personal injury (life, body, health) remains unaffected by the above provisions. 6.5. To the extent that sipgate’s liability is effectively excluded or limited, this also applies to the personal liability of employees, other staff, bodies, representatives and vicarious agents of sipgate. 6.6. sipgate’s obligation to provide services applies only if sipgate itself has been supplied with the corresponding upstream services in accordance with the contract and in due time and has not breached any duties of care in this respect. In the event of disruptions to performance due to force majeure, sipgate shall in any event be released from its obligation to perform. ### 7. Liability when customers use AI applications 7.1. sipgate provides AI applications that can be used by customers for automated communication with their end customers (e.g. initial telephone contact by AI agents). The systems comply with the requirements of the EU AI Act and are regularly checked for functionality and legal compliance. AI systems are highly complex systems that are subject to continuous development. Incorrect, undesired or misleading results cannot therefore be ruled out – even if the AI system operates within its specific parameters. 7.2. sipgate is not liable for damage arising from the use of the AI applications in the relationship between the customer and their end customers, provided that sipgate has properly provided and documented the systems. In particular, sipgate assumes no liability for incorrect information, misunderstandings or omitted notices arising from the AI in customer contact. 7.3. The customer is obliged to check the suitability of the AI applications for the respective use case before productive deployment and to ensure that the legal information, transparency and documentation obligations towards their end customers are fulfilled. 7.4. sipgate is liable only in cases of intentional or grossly negligent conduct and in the event of a breach of essential contractual obligations. Any further liability, in particular for indirect damages or loss of profit, is excluded. 7.5. The customer shall indemnify sipgate against all third-party claims asserted in connection with the use of the AI applications vis-à-vis end customers, insofar as these are not based on a breach by sipgate of statutory or contractual obligations. ### 8. Changes to charges, the General Terms and Conditions (GTC) and the service description 8.1. sipgate charges the customer the fees applicable at the time the contract is concluded and is generally bound by them. The agreed charges may only be increased by sipgate for the future in the following cases: * in the event of changes to the VAT rate, sipgate is entitled to adjust the charges accordingly to reflect the change, * if the Federal Network Agency or another authority mandatorily requires a fee increase, sipgate may change the fees in accordance with the requirements, and, * if third parties from whom sipgate obtains upstream services necessary for the provision of the services owed under this contract increase their prices, sipgate may pass on this price increase to the customer. A prerequisite for an increase in charges by sipgate is that sipgate informs the customer of the change in charges by email at least six weeks before it takes effect and explains the reason for the increase. 8.2. If the customer is a consumer (within the meaning of § 13 BGB), the customer is entitled, in the event of an increase in net charges, to a right of extraordinary termination, which takes effect at the time of the relevant change in charges. If the customer does not exercise this right of termination within four weeks of receipt of the notice of the increase in charges, the change shall be deemed approved. sipgate expressly points this out again in the notice of the increase in charges. In the event of changes to VAT, sipgate is entitled to adjust the charges accordingly to reflect the change, without this giving rise to a right of termination for the customer. 8.3. If the customer is an entrepreneur (within the meaning of § 14 BGB), sipgate is entitled, irrespective of no. 8.1, at its reasonable discretion and taking into account general market developments (in particular also internal upstream prices), to adjust the charges at any time for the future. This applies in particular insofar as sipgate’s purchase prices change. 8.4. sipgate is entitled to amend these GTC insofar as this does not affect essential provisions of the contractual relationship and this is necessary to adapt to developments that were not foreseeable when the contract was concluded and the failure to take them into account would significantly disturb the balance of the contractual relationship. Essential provisions are in particular those concerning the type and scope of the contractually agreed services and the term, including the provisions on termination. Furthermore, adjustments or additions to the GTC may be made insofar as this is necessary to eliminate difficulties in the performance of the contract due to gaps in the rules that arose after the contract was concluded. This may in particular be the case if case law changes and one or more clauses of these GTC are affected. If the change results in a deterioration for the customer, a change is only permissible on the condition that sipgate informs the customer of this by email no later than six calendar weeks before it takes effect. 8.5. The service description may be changed if this is necessary for an important reason, provided that the customer is not placed in a worse position compared with the service description included when the contract was concluded (e.g. maintenance or improvement of functionalities) and that it does not deviate significantly from it. An important reason exists if there are technical innovations in the market for the services owed or if third parties from whom sipgate obtains upstream services necessary for the provision of its services change their service offering. If the change results in a deterioration for the customer, a change is only permissible on the condition that sipgate informs the customer of this by email no later than six calendar weeks before it takes effect. 8.6. Intended changes to the GTC and the service description pursuant to clauses 8.5 and 8.6 will be communicated to the customer by email at least six weeks before they take effect. If the change to the GTC or the service description is detrimental to the customer, they have a right of extraordinary termination at the time the changes take effect. If the customer does not terminate in writing or by email within four weeks of receipt of the notice of change, the changes become part of the contract at the time they take effect. The customer is expressly informed of this consequence in the notice of change. ### 9. Maintenance and fault clearance service sipgate offers its customers the option at any time of accessing frequently asked questions and answers as well as various configuration instructions via its help center, contacting customer support in writing or by telephone via the contact form, and reporting disruptions, for example. ### 10. Final provisions 10.1. Deviating general terms and conditions of the customer shall not apply even if sipgate does not expressly object to them. 10.2. Free additional services provided by sipgate do not form part of the contract. sipgate may change and/or discontinue these services at its own discretion. This is subject to any other agreements with the customer. 10.3. The customer may transfer the rights and obligations arising from this contract to a third party only with sipgate’s prior written consent. 10.4. The use of products and services of sipgate GmbH in the territory of or by citizens of the United States of America (USA) is excluded. 10.5. The use of sipgate is excluded in those countries in which the use of sipgate’s service is not permitted. 10.6. The law of the Federal Republic of Germany shall apply exclusively between the customer and sipgate, as it applies between domestic persons, excluding the UN Convention on Contracts for the International Sale of Goods, unless mandatory law prescribes the applicability of another legal system. 10.7. The place of jurisdiction is Düsseldorf, provided the customer is a merchant. 10.8. sipgate is entitled to transfer the customer’s inventory data to third parties insofar as this is necessary for the purpose of assigning or collecting claims. Any legally permissible transfer of further customer data for the purpose of collecting claims remains unaffected. 10.9. sipgate is entitled to provide the services through third parties as subcontractors (subcontractors). 10.10. Locations created in the sipgate account are verified using a suitable procedure. ### 11. Customer information pursuant to the TKG #### 11.1. Emergency call (fixed line) The emergency numbers 110 and 112 can be reached via sipgate. These are activated for your stored address. The customer must check at regular intervals whether the personal or business details are correct and, if necessary, change them. Only if the name and address are correct at the time an emergency call is placed can proper emergency call functionality, in particular reachability of the nearest fire brigade or police station, be ensured. If you use sipgate from a location other than the stored address (nomadic use), emergency call service may be unavailable or only possible if you can inform the emergency call center of your location and your name. So-called “gurgle calls” are not possible. #### 11.2. Emergency call (mobile network) In Germany, an emergency call can only be placed to the pan-European emergency number 112 and the national emergency number 110 valid in Germany if a valid SIM card is inserted. Outside Germany, other rules may apply. For an emergency call to 112 and 110, information about the caller’s location may also be transmitted to the responsible emergency call answering point. In addition to the general emergency numbers 110 and 112, the customer can dial the SAR emergency call (sea rescue call) in the coastal areas of the North and Baltic Seas at the number 124 124. The SAR emergency call does not replace the usual marine radio services. #### 11.3. Conciliation procedure Customers in dispute with sipgate can initiate a conciliation procedure with the Federal Network Agency by submitting an application in accordance with § 68 TKG. The details of the conciliation procedure are regulated by the Federal Network Agency in a conciliation regulation which it publishes. EU Commission platform for online dispute resolution: [www.ec.europa.eu/consumers/odr](https://webgate.ec.europa.eu/odr/main/index.cfm?event=main.home.show\&lng=DE\&DeviceId=b06aff2e-fdc0-4bd9-9e23-ecaea52e6388\&SessionId=1767690360698) #### 11.4. Inclusion in public directories The customer may at any time request to be listed free of charge in a publicly accessible directory with their telephone number, surname, first name and address, or to have their entry deleted or amended. #### 11.5. Security or integrity of telephony and data processing systems When providing its services, sipgate places great importance on the security and integrity of its systems and data, as well as the correct functioning of the systems used. sipgate’s infrastructure is always kept up to date with the latest technology and complies with the current technical guidelines and applicable standards. In the event of breaches or identified vulnerabilities, measures are taken immediately to stop them and prevent future occurrences. This applies in particular both to potential attacks on sipgate’s network and to the protective measures proposed and implemented. sipgate has a security concept that has been approved by the Federal Network Agency. sipgate has implemented numerous technical and organizational measures to prevent security or integrity breaches as well as threats and vulnerabilities and to be able to respond to them at an early stage. Examples of such measures are: * sipgate regularly checks the technical devices used for possible security vulnerabilities in order to be able to identify and remedy possible threats or vulnerabilities at an early stage. * sipgate continuously keeps itself informed about published security vulnerabilities. * sipgate regularly monitors and maintains the technical devices used and has automatic monitoring for the essential systems 24 hours a day, 365 days a year, and can therefore respond quickly to acute security or integrity breaches at any time. * sipgate operates its own Network Operation Center, which monitors, among other things, the key network platforms and systems. * sipgate implements the current technical guidelines and standards aimed at applying technical measures to ensure integrity, i.e. among other things to be able to recognize corrupted data as such and, if necessary, carry out retransmission of the data. * sipgate informs the affected customers about a breach of security or integrity. * sipgate has implemented and integrated an emergency concept. If vulnerabilities are identified at sipgate in any form whatsoever, they are remedied immediately. #### 11.6. Blocking of certain number ranges The national number ranges 0137, 0138, 01212, 0181, 0185, 0188, 0900 and 118xx are blocked. Individual blocking of certain national, international number ranges and special numbers is not possible. #### 11.7. Suppression of caller ID The customer has the option of permanently or temporarily suppressing the display of their telephone number to the called party, if the function is supported by their terminal device. #### 11.8. Blocking of number ranges / services provided in addition to the connection The customer has the option of blocking certain number ranges under § 61(1) and is entitled to block the use and billing of services provided in addition to the connection via the mobile connection under § 61(2) TKG. #### 11.9. Use of the Call by Call and Preselection service of netzquadrat Gesellschaft für Telekommunikation mbH (01064) is possible. No other Call by Call and Preselection services are currently available. sipgate GmbH, Düsseldorf, October 16, 2025 sipgate service description: sipgate price list: sipgate privacy: [Requirements for use – Internet access sipgate](https://www.sipgate.de/nutzungsbedingungen) [Notes on placing emergency calls sipgate](https://www.sipgate.de/nutzungsbedingungen) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
