The SIP Trunk from willy.tel was first tested and released with SwyxWare 22.214.171.124.
The SIP Trunk from willy.tel is a SIP Trunk with user authentication, i.e. you receive information on user ID, user name and password. The names may differ, or you may 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.
In addition to the authentication information, the public IP address of the SwyxWare Server is also checked. You therefore need a static, public IP address from your ISP via which the SIP proxy of willy.tel communicates with SwyxWare.
The SIP Trunk from willy.tel can be used from SwyxWare 126.96.36.199 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.
The SIP Trunk from willy.tel is not released for central connection in the data center.
When creating the SIP trunk group, select the profile 'willy.tel (DE)'.
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: +41 40 123456780 ... +41 40 123456789
In this case, the SIP URI must be entered in the format +494012345678*@*.
Afterwards, the LinkMgr service has to be restarted.
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.
- Incoming/outgoing national /international calls
- Correct Calling Line Identification (CLI) on national / intenational calls
- CLIP No Screening

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.
