SIP Provider Swisscom (CH) - Business Connect

General

The Business Connect SIP Trunk was first tested and released with a SwyxWare2013 R5.

The Swyx partner orders a so called ConnectBox for the customer from the Swisscom. This box has firstly the task to control the SIP signaling between the box and the Swisscom and secondly to offer the SIP trunking functionality. The SwyxWare does not directly register at Swisscom but at the ConnectBox instead. Together with the ConnectBox, the customer/partner has received the assigned numbers and log-in information in order to connect to the web interface of the box.
It must be assured that the ConnectBox in the cusomer's network is configured with a static IP address.

Platforms

SwyxWare

The Business Connect SIP Trunk from Swisscom can be used without restrictions from SwyxWare 2013 R5.

SwyxON

Because of the dependency from the locally installed ConnectBox, using the Business Connect SIP Trunk from Swisscom in a SwyxON environment is not supported.

Configuration of the ConnectBox

1. Logon through a browser at the ConnectBox
2. Start of the Swyx IP-PBX Wizards. Through the wizard, the SIP trunk is configured.
3. Authentication User Name and Password must be assigned.
4. The static IP address of the ConnectBox must be entered as SIP Domain. The first number of the assigned number range in national format must be configured as BC Basenumber.

Disclaimer

Verifying interoperability between different SIP providers and the Swyx solution is part of the Enreach Technology Alliance Programme (TAP) tasks. Due to different implementations of the SIP RFCs, it is necessary to determine and provide an individual configuration for each SIP provider.

Within the TAP, Enreach tests a large number of national and international SIP providers in order to make statements about the interoperability with the Swyx solution and the functional scope of the respective SIP trunk. These results and, if needed, configuration advice are published in Help Center articles.

Enreach is in close contact with selected SIP providers to ensure a quick troubleshooting in case of incompatibilities. In addition, tests are repeated at regular intervals to ensure consistent quality.

Despite regular retests it cannot be excluded that incompatibilities with the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid. After creating the trunk group or SIP trunk, the profile settings should be compared with the provider's information and adjusted accordingly in case of deviations.

However, should incompatibilities or problems occur with a tested SIP trunk, no claims for recourse against Enreach GmbH can be derived from this. In such cases, you can contact Enreach Support via your specialist dealer.
