The HSIPT trunk from British Telecom (BT) was first tested and released with a SwyxWare 2015 R40.
The HSIPT trunk from (BT) trunk is a SIP trunk with user authentication. You have received information about UserID, UserName and UserPassword, whereas the nameing may differ.
The HSIPT Trunk from BT can be used according to the settings listed below from SwyxWare 2015 R40.
The HSIPT Trunk from BT is not released for central connection in the data center.
During creation of the SIP Trunkgroup, the profile 'British HSIPT Telecom (UK)' must be selected.
BT is operating with a number of different servers. Therefore it is not possible to preconfigure the Registrar server, the Proxy Server and the Realm in the "SIP" tab of the Trunkgroup Properties dialog. In this field, please enter the information that BT has named you.
In case that the SwyxWare server is running with a private IP address and the public IP address is provided by NAT gateway, it is necessary to configure a STUN server in the properties of the SIP trunk group, under the tab 'SIP'. A list of public STUN servers can e.g. be found at http://www.voip-info.org/wiki/view/STUN.

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the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid.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