# What is sipgate trunking?

{% hint style="info" %}
Update: The [trunk detail page](#trunking-detailseite) has been cleaned up and made clearer.
{% endhint %}

sipgate trunking connects your VoIP phone system to the public telephone network via sipgate. It does not register each individual phone, but the entire phone system for VoIP communication. Incoming and outgoing calls work just like on a normal PBX/PMx connection.

Since we support the SIP standard, both all dialed phone numbers in your phone system can be evaluated and any desired outgoing caller ID can be set. You also have a wide selection of end devices to choose from. If you have any questions about setting up the end devices, please contact the system manufacturer.

You can find more information in our product description [sipgate trunking.](https://www.sipgatetrunking.de)

## What happens with trunk in and trunk out?

With trunk in, incoming and outgoing calls take place over the internet; a landline connection is no longer required. If you want to continue using your existing number range, you must port the numbers to sipgate for this purpose.

With trunk out, the system connection can remain on the landline network. Incoming calls are then delivered as usual via the landline network. Only outgoing calls use the sipgate connection. Outgoing calls therefore take place over the internet, and the caller ID of the landline connection can be signaled. The person being called sees no difference from a call over the landline network.

## What trunking plans are available?

The different trunking contracts differ in the number of usable channels. This means that the number of possible parallel calls is defined in the respective contract.

With sipgate trunking, you can choose between three different contract models:

* **sipgate trunking 2** - includes 2 channels (incoming) and 100 outgoing calls.
* **sipgate trunking 10** - includes 10 channels (incoming) and 100 outgoing calls.
* **sipgate trunking 50** - includes 50 channels (incoming) and 100 outgoing calls.

The contracts each have a term of one month. A contract can be canceled for the following month. Switching contracts is possible at any time and very easily with a click. You can find a detailed price list and more information on our [website](https://www.sipgatetrunking.de/tarife).

## trunk detail page

You can find an overview of your sipgate trunks in the logged-in area under **Account management** → **Trunks**. On this **overview page** all set up trunks are listed. You can also see the most important information at a glance, such as location, status, used call minutes, and call blocks set.

With a click on one of the available trunks, you can view additional **details** such as emergency location, fallback number, and all numbers assigned to the trunk. Individual trunks can be selected, renamed, and if necessary deleted with a click on the overview page.

The phone numbers of the individual trunks are now displayed in sorted order in a collapsible menu. Another new feature is that the online status of the individual trunks is displayed. We have also improved the selection of phone numbers for individual trunks. From now on, you can see which phone numbers are already in use and which are still available. In addition, booking new phone numbers here has been simplified.

The trunk detail page can now also be viewed easily on tablets and smartphones.
