Information und configuration hints for SIP provider Swyx Trunk (Germany).


General information

The Swyx Trunk was first tested and released with SwyxWare

The Swyx Trunk is a SIP trunk with user authentication. From the operator portal, you need the channel name to be configured as user ID and user name in the SwyxWare and password.


SwyxWare: The Swyx Trunk can be used without restrictions from SwyxWare on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.

SwyxON: The Swyx Trunk is suitable for central connection in the data center.


In the operator portal, the Swyx profile has to be selected. Please be aware that changes in the settings must be reflected by the SwyxWare settings and adopted accordingly.

When creating the SIP trunk group, select the profile 'Swyx Trunk (DE)'. If the profile is not included in the corresponding list, you can download the required CustomProviderProfiles.config for SwyxWare at the end of this article. For more information about using this file, see Configuration and Adaptation of SIP Providers via Provider Profiles (kb3436).
