General
The SIP Trunk Flexx from NFON is available throughout Europe.
The SIP Trunk Flexx from NFON was first tested and released with SwyxWare 14.00.
NFON offers a SIP trunk with user authentication, i.e. you receive information on UserID, UserName and UserPassword from NFON, whereby the designations can also differ, or you only receive the user name and password. In this case, the UserID is identical to the UserName.
NFON has its own template for the SwyxWare. It is therefore important to assign the "Swyx" template to the PBX endpoint when setting it up in the NFON customer portal.
Platforms
SwyxWare
The SIP Trunk Flexx from NFON can be used throughout Europe according to the settings listed below from SwyxWare 14.00 on. If an earlier version of SwyxWare is used, incompatibilities cannot be ruled out and use is at your own risk.

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the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid.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