SIP Provider SFR (FR)

General

The SIP Trunk from SFR (FR) was first tested and released with a SwyxWare 2015.

A SIP trunk from SFR (FR) can only be used in combination with an internet access from SFR. The customer network therfore usually is within the SFR network.

The SIP communication between the SFR SIP proxies and the SwyxWare has to be established through port 5060. Since the SwyxWare per default uses port 65002 to communicate with a SIP provider, it is necessary to install the appropriate service (LinkMgr) on a separated server and to change the SIP port accordingly.

SFR (FR) is offering registerless SIP trunks. This means that the authentication is based on the public IP address of the LinkMgr server. Therefore, you need a static, public IP address from SFR assigned to the LinkMgr server.

Platforms

SwyxWare

The SIP Trunk from SFR can be used according to the settings listed below from SwyxWare 2015 on.

SwyxON

The SIP Trunk from SFR is not released for central connection in the data center.

Configuration 

During creation of the SIP Trunkgroup, the profile 'SFR (FR)' has to be selected.

SFR is operating with a number of different servers. Therefore it is not possible to preconfigure the Proxy Server in the "SIP" tab of the Trunkgroup Properties dialog. In this field, please enter the IP address that SFR has named you.

For additional information, it is possible to download a configuration guide at the end of this article.

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the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid.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