I think that’s getting me close. I’m trying to get (or recreate) the FROM and TO lines of the header, from a system running PJSIP. I think if I use CHANNEL to get local_uri and local_tag I can recreate a FROM line like:
FROM=<URI>;tag=TAG And if I use CHANNEL to get remote_uri and remote_tag I can recreate a FROM line like: TO=<URI>;tag=TAG Would it be correct to assume that with this info (and ip:port info) I should be able to send a UDP SIP message from the PBX to the UA which appears to be part of the current call dialog? I realize this is an odd thing to do, but I’m just interested in technical feasibility at this point. Before I try to code this I want to ensure I’m not missing something stupid.

I also read (on stackoverflow) that the PJSIP_HEADER function will only return the headers from the INVITE of the inbound channel. If that’s correct, how would I get the headers from the outbound channel (second leg of the bridged call) INVITE ? Or will PJSIP_HEADERS() in fact return the header from either inbound out outbound legs? The answer is, you can't. There are SOME protocol level things accessible using CHANNEL[1] but that's it.
