Swyx Trunk (DE)

General

The Swyx Trunk was first tested and released with SwyxWare 11.25.0.0.

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.

Platforms

SwyxWare

The Swyx Trunk can be used without restrictions from SwyxWare 11.25.0.0 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.

Configuration

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 an encrypted connection needs to be created, the profile 'Swyx Trunk TLS (DE)' has to be selected.

SIP URIs

When creating the actual SIP trunk, a SIP URI must be entered after configuration of the phone number range so that incoming calls can be assigned. The assigned number block must be taken into account in the correct format.

Example:
Number block: +49 231 9988776600 ... +49 231 9988776699
In this case, the SIP URI must be entered in the format 023199887766*@*.

Codec configuration

For T.38 FAX transmission, the checkbox "Remove T.38 codec from initial invite" has to be selected in the codec dialog.

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the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid.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.
