> Follow on from issue Asterisk-24509
> If setting up a trunk to an IMS where the registrar is behind a P-CSCF and not reachable directly, after initial registration, all INVITE and OPTION messages use the proxy domain and not the registrar domain. These are ignored by the P-CSCF and timeout after defined retransmits.
> FromDomain is set to REGISTRAR and used in FROM header, but proxy is used in Request-Line and To header.
> OutboundProxy cannot be set to REGISTRAR as DNS fails.
> Impact is that Outbound fails, and Inbound works until the registrar drops because of no keep-olives. Trunk is unusable.
> X-Lite, and Telephone can both be configured to work correctly (i.e. use the correct domain in RequestLine and To:Header.
> Registration is not an issue.
