In May 2020, HFO Telecom became part of the telephone company Gamma. Since March 2022, the product names have been adapted.
The actual tests were carried out with the HFO NGN SIP Trunk. Only the product name was modified.
The NGN accesses from Gamma Communication were first tested and released with a SwyxWare 11.00.0.0.
The NGN accesses from Gamma Communication are SIP trunks with user authentication.You have received information from Gamma Communication 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 Gamma Communication can be used from SwyxWare 11.00.0.0 on.
The SIP Trunk from Gamma Communication is suitable for central connection in the data center.
During creation of the SIP trunkgroup, profile 'HFO Telecom (DE)' has to be selected.
From SwyxWare 13.25, the profile 'Gamma ex. HFO (DE)' has to be selected.
During the following creation of the actual SIP trunk, when providing the registration information, in the fields 'User ID' and 'Username' the 'Benutzername' from the Gamma Communication documents have to be entered.
For connections on SwyxON, it is necessary to assign a SIP URI to the trunk so that incoming calls can be assigned to the correct 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 04012345678*@*.

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.
