[asterisk-dev] Asterisk 16. PJSIP. INVITE. "Contact" field and FQDN

[KoltogyanU2 SergeyU2]

I found a place in res_pjsip.c, where a new "contact_user" is added.
This is file   ./res/res_pjsip.c  string 3514
pj_strdup2(dlg->pool, &sip_uri->user, endpoint->contact_user);

I Tried this:
pj_strdup2(dlg->pool, &sip_uri->user, "XXYYZZ");
So it works - it changes the ContactUserName ( on the left of @ ).

But I do not find a place where I can enter FQDN, instead of the IP address.
Someone can tell - in which place of the source text to make a change, what was right of @ was not an IP Address, but a FQDN?

A hostname is not supported with the external_* options, for placement into the messages. It gets resolved down to the IP address. Placing a hostname into the Contact header URI host is not currently supported out of the box. The Contact stuff is handled within res_pjsip.c, the easiest option being to look for use of "contact_user" as that already modifies the user portion and using that as a base for any modification.
