I am now using Asterisk 13 and have implemented PJSIP. Unfortunately, CHANNEL(pjsip,target_uri) does not give me what I need. In fact, it seems to be incorrect, in addition to not being what I need. It appears to give me a portion of either the "From: " or "Contact: " SIP Header.
I would rather not publicly post the entire SIP packet, so I have sanitized my packet; I have replaced a local TN that is the caller id of the calling line with the characters “NPANXXXXXX” and I have changed two IP addresses with “aaa.bbb.ccc.ddd” and “eee.fff.ggg.hhh”, respectively. Here is the SIP packet:
<--- Received SIP request (1100 bytes) from UDP:aaa.bbb.ccc.ddd:5060 --->

And when I do the following in extensions.ael:
NoOP(${CHANNEL(pjsip,target_uri)});
NoOP(${CHANNEL(pjsip,local_uri)});
NoOP(${CHANNEL(pjsip,remote_uri)});
NoOP(${CHANNEL(pjsip,local_addr)});
NoOP(${CHANNEL(pjsip,remote_uri)});
Then I get:
-- Executing [7002015278@SOMECONTEXT:6] NoOp("PJSIP/server.domain.tld-0000000c", "sip:NPANXXXXXX@aaa.bbb.ccc.ddd") in new stack

-- Executing [7002015278@SOMECONTEXT:10] NoOp("PJSIP/server.domain.tld-0000000c", "<sip:NPANXXXXXX@aaa.bbb.ccc.ddd>") in new stack
Whereas, the information I’m trying to get is the full RURI from the INVITE request:
sip:7002015278@10.1.16.117:5060;transport=udp;role=orig
Do you have any further suggestions on how I might retrieve this info?
I appreciate your help so far, and any help you can provide. Thanks!
