### 1. Conclusion and termination of the contract

#### 1.1. 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 shall be deemed 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 then. The customer is bound by his 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 stated 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 stated 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 his obligations under the contractual relationship and it is unreasonable for sipgate to wait for the expiry 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 telephone number assigned to him abusively and/or
* if insolvency proceedings are opened against the customer's assets or the customer files an application to open insolvency proceedings and/or
* debit returns occur after direct debits.

1.3.2. In addition, sipgate is entitled to extraordinary termination in the event of changes to the legal basis of this contract or orders and/or orders issued by authorities, courts or other holders of public authority relating to the contract, provided that these result in it becoming unreasonable for sipgate to remain bound by the contract.

1.3.3. The customer's statutory right to extraordinary termination for good cause remains unaffected.

#### 1.4. sipgate credit balance upon termination of the contract

1.4.1. If, at the time the termination takes effect, the customer has a credit balance on his sipgate account, sipgate undertakes to reimburse this to the customer upon corresponding request. The customer can submit the request via his sipgate account. Reimbursement by sipgate is made by way of a credit to the bank account or credit card account specified by the customer.

1.4.2. Any other reimbursement of the sipgate credit balance is excluded.

#### 1.5. Inactive accounts

If the customer has a sipgate account that has not been 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 obligations to cooperate

2.1. It is the customer's responsibility to maintain an internet access suitable for use with sipgate (see requirements for use – internet access). If this is not the case, the mutual obligations to provide services arising from the contractual relationship remain unaffected.

2.2. The customer must take all necessary and customary security measures against unintended and abusive use of his sipgate connection by third parties. If the customer becomes aware of unintended or abusive use, he must inform sipgate immediately.

2.3. sipgate handles essential communication processes (including those relevant to the contract) via email. The customer undertakes to provide his own valid email address when registering with sipgate and to check it regularly, as well as to inform sipgate immediately of any changes to his email address.

2.4. If changes arise that affect the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed immediately. This obligation to report 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 procedure, bank 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 respective valid version. The customer is obliged not to misuse the telecommunications services offered by sipgate for purposes that conflict with 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 provided by sipgate.

2.7. The customer undertakes to keep access data to his sipgate account and user accounts as well as access data to the sipgate 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. his employees), he must inform them of the obligation to keep the access data confidential and secure and obligate them accordingly.

Private customers in 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 his telephone number may 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 remains unaffected.

2.9. sipgate is entitled to change the customer's telephone numbers,

* if the customer agrees to the change,
* if this is required by legal provisions or official measures (in particular the Telecommunications Numbering Ordinance or decisions of the Federal Network Agency),
* or if corresponding economic or legal constraints exist that sipgate cannot resolve otherwise with reasonable effort.

2.10. The customer is not permitted to pass on sipgate services rendered to him commercially to third parties without sipgate's consent.

2.11. If there is misuse by the customer or a user authorized by him (e.g. violations of 2.5., 2.6., 2.10. or comparable violations) and the customer does not cease the misuse within a reasonable period despite a request from sipgate, sipgate is entitled to block his sipgate connection or – where applicable – delete user accounts created by the customer. If the customer is responsible for the blocking or deletion, sipgate will charge the customer for the costs of the blocking/deletion. The customer is obliged to pay the basic fees incurred during a blocking if he is responsible for the blocking.

### 3. Connection charges

3.1. The customer is obliged to pay for any use of his connection for which he is responsible.

3.2. The customer is also obliged to pay the charges caused by the user or co-user. This also applies in the case of abusive use, unless he proves that he is not responsible for any breach of duty.

3.3. The obligation to pay remuneration does not apply insofar as facts justify the assumption that third parties have influenced the connection charge invoiced by unauthorized changes to public telecommunications networks.

3.4. The charges for the VoIP service are based on the price list valid 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 under the respective 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: Under this procedure, the customer first pays an amount of his choosing to sipgate (sipgate credit balance) and may only use chargeable sipgate products after the payment has been received and in accordance with his sipgate credit balance. 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 balance 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 payment only after performance by sipgate based on 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 his current bank details or credit card details are stored in his sipgate account. If this is not the case, or if the customer revokes the direct debit authorization or the authorization to charge the credit card, a negative 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 the customer by email to settle his negative balance.

#### 4.2. Payment methods

4.2.1. In addition to bank transfers, sipgate offers direct debit and credit card payments, provided the customer gives his consent. Participation in the Autoprepay method is only possible, however, if the customer consents to recurring direct debit or credit card payments. The customer must declare his consent when activating the Autoprepay billing procedure in his 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 notice period for pre-notification (Pre-Notification) 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 he is 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 and fees of sipgate's bank) and debit them from the account balance, unless the customer proves that no damage has occurred at all or that it is significantly lower.

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 shall only take effect if the customer has sufficiently specified the intended purpose (in particular the invoice number or a comparable, unique 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) alongside direct debit or credit card payments.

#### 4.3. Form of invoice

4.3.1. sipgate issues invoices exclusively as PDF files by email or for download. Issuing an invoice in paper form is not possible.

4.3.2. The customer agrees to receive his invoice by email and is informed that confidential data transmission over the internet cannot be guaranteed. For this reason, sipgate invoices do not contain a detailed connection record. This can be retrieved separately by the customer.

4.3.3. The mandatory information in the invoice (Section 14(4) VAT Act) is included in the invoice on the basis of the information provided by the customer in his sipgate account. The customer is obliged to keep this information up to date. sipgate is not obliged to issue 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) become due on the 1st day of each month (or period), unless otherwise stipulated in the service description. If 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, in accordance with Section 61 (3) et seq. TKG, to suspend the service.

4.4.4. If the customer is a consumer (within the meaning of Section 13 BGB) and is in default, interest shall 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 Section 14 BGB), eight percentage points above the base interest rate shall be charged. sipgate reserves the right to assert further claims due to payment default (e.g. reminder fees).

4.4.5. After eight weeks from receipt of the invoice, sipgate is entitled to delete the connection data on which the invoice is based, which is why subsequent objections can no longer be taken into account. This also applies accordingly if the customer requests early 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 is stored in full.

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. The customer must raise objections to the amount of the invoice in writing no later than eight weeks after receipt of the invoice.

If the customer has a credit balance with sipgate against which sipgate offsets basic charges 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 were incurred. The amount of the offsetting amounts can be found in the itemized connection 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 the credit balance are excluded insofar as the relevant traffic data have already been deleted within the statutory periods (eight weeks) or at the express request of the customer before objections were raised.

4.5.3. If objections are not raised within the eight-week period under No. 4.5.1, the invoice/offsetting against the credit balance shall be 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 time, in the case of an overpayment there shall first be an offsetting 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 the handling of 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-Telemedia Data Protection Act (TTDSG). Personal data shall only be collected, processed or used if the data subject has consented or if the TTDSG or another legal provision orders or permits this.

5.2. Data processing is therefore particularly permissible insofar as it is necessary. This is necessary for the establishment and structuring of the contractual relationship (inventory data), for the provision of telecommunications services (connection data), and for their billing (billing data).

5.3. sipgate maintains telecommunications secrecy in accordance with the statutory requirements.

5.4. Detailed information on the handling of personal data by sipgate can be found in our [privacy policy](http://www.sipgate.de/team/datenschutz)which is also part of the sipgate GTC.

5.5. The customer instructs sipgate to maintain a monthly itemized connection record, which he can access via the administrator account. This record lists all chargeable connections individually, including the date, destination number, start and duration of the connection, and the charge for the individual connection. The telephone numbers of the connections are either abbreviated by the last three digits or given in full length according to the customer's choice. The customer can also completely deactivate the itemized connection record in his administrator account. If the customer does not exercise his right of choice, the full listing is used.

The customer undertakes to inform all current and future co-users of his sipgate account or, in the case of business use, all current and future employees immediately and to comply with the co-determination rules.

5.6. The customer instructs sipgate to store basic data (time, duration) of telephone calls, faxes and SMS messages sent or received via sipgate, independently of the itemized connection record, for the call list / event list and to make it available to the respective user on his user interface.

5.7. sipgate deletes customer data if the customer gives a corresponding order, 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's liability is limited to a maximum amount of €12,500 per customer. In relation to all 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 the ratio in which the sum of all compensation claims stands to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally.

6.2. Liability for consequential costs caused by emergency calls outside the specified place of residence or business is excluded.

6.3. Otherwise, sipgate is only liable for gross negligence or intent, unless there is a breach of a material 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 damage as was 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. Insofar as 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 perform only applies if sipgate itself has been supplied with the corresponding advance services in accordance with the contract and on time and has not breached any due diligence obligations in this respect. In the event of service disruptions caused by force majeure, sipgate shall in any case be released from its obligation to perform.

### 7. Liability in the use of AI applications by customers

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 specifications.

7.2. sipgate is not liable for damage caused by the use of AI applications in the relationship between the customer and his 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 AI applications for suitability for the respective use case before productive use and to ensure that the statutory information, transparency and documentation obligations toward his end customers are fulfilled.

7.4. sipgate is only liable in cases of intentional or grossly negligent conduct and in the event of a breach of material contractual obligations. Any further liability, in particular for indirect damage 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 towards 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 fees may only be increased by sipgate with effect for the future in the following cases:

* in the event of changes to the VAT rate, sipgate is entitled to adjust the charges accordingly,
* insofar as the Federal Network Agency or another authority makes a binding demand for a fee increase, sipgate may change the charges in accordance with the requirements, and
* insofar as third parties from whom sipgate obtains necessary advance services for the provision of the services owed under this contract increase their prices, sipgate may pass on this price increase to the customer.

The prerequisite for an increase in charges by sipgate is that sipgate notifies 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 Section 13 BGB), the customer has a special right of termination in the event of an increase in net charges, 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 notification of the fee increase, the change shall be deemed approved. sipgate expressly points this out again in the notification of the fee increase.

In the event of changes to VAT, sipgate is entitled to adjust the charges accordingly without this giving rise to a right of termination for the customer.

8.3. If the customer is an entrepreneur (within the meaning of Section 14 BGB), sipgate is entitled, regardless of No. 8.1, at its reasonable discretion and taking into account general market developments (in particular also internal advance service prices), to adjust the charges at any time with effect 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 unforeseeable at the time 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 supplements 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 be the case in particular if case law changes and one or more clauses of these GTC are affected by this. If the change results in a deterioration for the customer, a change is only permissible on the condition that sipgate notifies the customer by email at least six calendar weeks before it enters into force.

8.5. The service description may be changed if this is necessary for good cause, the customer is not placed at a disadvantage compared to the service description included at the time of contract conclusion (e.g. retention or improvement of functionalities), and there is no significant deviation from it. Good cause exists if there are technical innovations on the market for the services owed or if third parties from whom sipgate obtains necessary advance services 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 notifies the customer by email at least six calendar weeks before it enters into force.

8.6. Intended changes to the GTC and the service description pursuant to clauses 8.5 and 8.6 will be notified to the customer by email at least six weeks before they take effect. If the change to the GTC or the service description is disadvantageous to the customer, the customer has a special right of 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 notification 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 notification of change.

### 9. Maintenance and fault correction service

sipgate always offers its customers the opportunity to access frequently asked questions and answers, as well as various configuration instructions, via its help center, and to contact customer support in writing or by telephone via the contact form, for example to report faults.

### 10. Final provisions

10.1. Deviating general terms and conditions of the customer also do not apply even if sipgate does not expressly object to them.

10.2. Free additional services provided by sipgate are not 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 only transfer the rights and obligations arising from this contract to a third party 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 the sipgate service is not permitted.

10.6. The law of the Federal Republic of Germany applies 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, insofar as 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. The legally permitted transmission of further customer data for the purpose of debt collection remains unaffected.

10.9. sipgate is entitled to provide the services through third parties as 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 (landline)

The emergency numbers 110 and 112 can be reached via sipgate. These are activated for the address stored with your account. The customer must check at regular intervals whether the personal or business details are correct and change them if necessary.

Only if the name and address are correct at the time an emergency call is made can proper emergency call functionality, in particular the accessibility of the nearest fire brigade or police station, be guaranteed. If you use sipgate from a location other than the stored address (nomadic use), emergency service may not be available at all or only if you can tell the emergency center your location and your name. So-called “gasping calls” are not possible.

#### 11.2. Emergency call (mobile)

In Germany, an emergency call to the Europe-wide emergency number 112 and the national emergency number 110 valid in Germany can only be made with a valid SIM card inserted. Outside Germany, other rules may apply. In the event of an emergency call to 112 and 110, location details of the caller may also be transmitted to the responsible emergency call center. In addition to the general emergency numbers 110 and 112, the customer can dial the SAR alarm call (maritime emergency call) in the coastal areas of the North and Baltic Seas under the number 124 124. The SAR alarm call does not replace the usual maritime radio services.

#### 11.3. Conciliation procedure

Customers in dispute with sipgate may initiate a conciliation procedure at the Federal Network Agency by submitting an application pursuant to Section 68 TKG.

The details of the conciliation procedure are regulated by the Federal Network Agency in a conciliation code, which it publishes.

European 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\&ampDeviceId=b06aff2e-fdc0-4bd9-9e23-ecaea52e6388\&ampSessionId=1767690360698)

#### 11.4. Inclusion in public directories of subscribers

The customer may at any time request to be entered free of charge in a publicly accessible directory of subscribers with his telephone number, surname, first name and address, or to have his 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 latest technical guidelines and applicable standards. In the event of breaches or identified vulnerabilities, measures to prevent and avoid future occurrences are taken immediately. This applies in particular to both potential attacks on sipgate's network and the proposed and implemented protective measures. sipgate has a security concept approved by the Federal Network Agency.

sipgate has implemented numerous technical and organizational measures in order to be able to prevent security or integrity breaches as well as threats and vulnerabilities and respond to them at an early stage.

Examples of such measures are:

* sipgate regularly checks the technical equipment used for possible security vulnerabilities in order to identify and remedy potential threats or vulnerabilities at an early stage.
* sipgate continuously monitors published security vulnerabilities.
* sipgate regularly monitors and maintains the technical equipment used and has automatic monitoring for the essential systems 24/7, 365 days a year, so that it can react quickly to acute security or integrity breaches at any time.
* sipgate operates its own Network Operation Center, which monitors, among other things, the essential network platforms and systems.
* sipgate implements the current technical guidelines and standards that are aimed at implementing technical measures to ensure integrity, i.e. among other things, to be able to identify corrupt data as such and, if necessary, carry out a renewed data transmission.
* sipgate informs the affected customers of a breach of security or integrity.
* sipgate has implemented and integrated an emergency concept. If any vulnerabilities are identified at sipgate in any form, 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 numbers and number ranges as well as certain special numbers is not possible.

#### 11.7. Suppression of caller ID

The customer has the option of permanently or temporarily suppressing the display of his telephone number to the called party, if the function is supported by his terminal device.

#### 11.8. Blocking of number ranges/services provided in addition to the connection

The customer has the option to block certain number ranges pursuant to Section 61(1) and is entitled to have the use and billing of services provided in addition to the connection blocked via the mobile connection pursuant to Section 61(2) TKG.

#### 11.9. The use of the call by call and preselection service of netzquadrat Gesellschaft für Telekommunikation mbH (01064) is possible. Further call by call and preselection services are currently not available.

```

The question should be specific, self-contained, and written in natural language.
