The SIP trunk of A1 Telekom was first tested and released with SwyxWare 12.00.
|Due to extensions on the provider side, a connection can only be made from SwyxWare 12.00 and a correspondingly adapted profile.
The use with an older SwyxWare version and the integrated profile is therefore no longer possible.
The SIP trunk of A1 Telekom is a SIP trunk with user authentication, i.e. you get information about user ID, user name and password from A1 Telekom. The names may differ, or you will only receive a name or ID with password. In this case the user ID is identical to the user name when configuring the SIP trunk in SwyxWare.
The SIP Trunk of A1 Telekom can be used without restrictions from SwyxWare 12.00. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.
The SIP Trunk of A1 Telekom is not suitable for central connection in the data center due to the dependency from the internet access.
During creation of the SIP trunk group, profile 'A1 Telekom (AT)' must be selected.
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.
Number block: +43 1239988776600 ... +43 1239988776699
In this case, the SIP URI must be entered in the format +4312399887766*@*.
During creation of the actual trunk, in the codec configuration dialog, T.38 has to be deselected as supported codec. This step could also be performed afterwards in the properties of the SIP trunk, underneath the 'Codecs' tab.

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.
