Hi, Has anyone managed to get hold of an XML config file for a BT SIP trunk? They are listed as a SIP Trunk Provider (https://www.3cx.com/partners/sip-trunks/uk/), but they do not appear in the list of available SIP providers, even in the latest update of v15. BT Wholesale apparently can't provide a copy of the XML file and I can't make the connection work correctly with the Generic SIP config. I can't see the point of BT being listed as a SIP trunk provider if it doesn't work! Thanks in advance.
