SIP Provider T-Mobile Austria (AT)

General

The Business Voice SIP Trunk from T-Mobile Austria was first tested and released with a Swyxware 12.00

T-Mobile Austria is offering the Business Voice SIP Trunk with user authentication. You have received information about UserID, UserName and UserPassword, whereas the naming may differ, or you might have only received UserName and -password. In this case, UserID and UserName are identical. Besides, you need an IP address which was assigned by UPC and which gets connected to the SIP trunk.

The actual interoperability tests were performed by the company Data-Way, not by Swyx TAP.

Plattforms

SwyxWare

The Business Voice SIP Trunk from T-Mobile Austria can be used without restrictions with SwyxWare 12.00 or higher. When using an earlier version of SwyxWare, incompatibilities cannot be excluded and use is at your own responsibility.

SwyxON

The Business Voice SIP Trunk from T-Mobile Austria is not suitable for central connection in the data center due to its dependence on the assigned IP address.

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the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid.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