The HSIPT trunk from Brirtish Telecom (BT) trunk is a SIP trunk with user authentication. You have received information about UserID, UserName and UserPassword, whereas the nameing may differ.
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.
Important: From SwyxWare 11.00 on, the provider profile for British Telecom HSIPT (UK) is available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.
During creation of the SIP Trunkgroup, the profile 'British HSIPT Telecom (UK)' must be selected. A detailed configuration guide can be downloaded at the end of this article.
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.
