[asterisk-bugs] [JIRA] (ASTERISK-25986) chan_sip: Wrong request line with IMS and Proxy - Asterisk should be using loose routing, but it isn't?

Richard Mudgett updated ASTERISK-25986:
---------------------------------------

    Description: 
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-alives. 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.
