The SIP Trunk from Deutsche Telefon was first tested and released with a SwyxWare 2015 R40.3.0
Deutsche Telefon is offering a 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.
The SIP Trunk from the Deutsche Telefon can be used according to the settings listed below from SwyxWare 2015 R40.3.0 on. When using an earlier version of SwyxWare, incompatibilities cannot be excluded and the use is at the user's own risk.
During creation of the SIP trunk group, profile 'Deutsche Telefon (DE)' must be selected.
In order to assign incoming calls to the correct trunk, it is necessary to configure a SIP URI for the trunk. The assigned number block and the numberformat must be considered.
Numberblock: +49 231 9988776600 ... +49 231 9988776699
In this case, the SIP URI must be entered in the format 023199887766*@*.
In the codec dialog for FAX transmission via T.38 the two options "Remove T.38 codec from initial invite" and "Prohibit T.38 reinvite by sender" must be activated.
- Incoming/outgoing national calls
- Incoming/outgoing international calls
- Correct Calling Line Identification (CLI) on national and international calls
- CLIP No Screening
- Holding and retrieving calls
- Toggeling between two calls
- Call transfer
- Mutually supported codecs:
- Incoming/outgoing DTMF signaling in accordance with via RFC2833
- Fax transmission via T.38

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.
