RichardDCG Posted December 16, 2021 Report Share Posted December 16, 2021 I may well be going blind, where can I set the SIP trunk to use TCP and not UDP? I can see the "Proposed SIP transport protocol" but this seems to be endpoint specific and not trunks? Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted December 16, 2021 Report Share Posted December 16, 2021 Use an outbound proxy like sip:provider:5060;transport=tcp. The PBX follows RFC3263. Quote Link to comment Share on other sites More sharing options...
