[asterisk-bugs] [JIRA] (ASTERISK-25986) Wrong request line with IMS and Proxy

[Steve Akerman (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=230482#comment-230482 ] 

Steve Akerman commented on ASTERISK-25986:
------------------------------------------

Is the issue actually that Asterisk stores the registration with the proxy and not with the registrar. See below registry entry.

{noformat}
Host                                    dnsmgr Username       Refresh State                Reg.Time                 
internet.p-cscf.sfr.net:5064            Y      +3399XXXXXXXXXX      3585 Registered           Wed, 04 May 2016 07:37:02
{no format}

It then uses this host in all subsequent messages?

> 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.
