Ah, thank you for that! I had tried calling msg_apply_changes() after using add_path(), but didn't realise that it's dependent on relay rather than just adding it to the existing message lumps. However, to your point, the documentation does say that the "outgoing" interface address is populated by add_path*(), which of course means that has to be known.
Nevertheless, Path is not being replicated. Furthermore, after upgrading to 5.1, I am not getting any replication of remote contacts whatsoever, even with no path involvement. And "socket" is still not an attribute of the DMQ messages being passed: KDMQ sip:usrloc@100.2.160.20 SIP/2.0 Via: SIP/2.0/UDP 100.2.128.20;branch=z9hG4bKc0ec.d07b9da1000000000000000000000000.0 To: <sip:usrloc@100.2.160.20> From: <sip:usrloc@100.2.128.20:5060>;tag=68a630e496181361fe35a2f5a89714ad-02ab CSeq: 10 KDMQ Call-ID: 4cf0c5e5257bcb22-6408@100.2.99.211 Content-Length: 461 User-Agent: kamailio (5.1.1 (x86_64/linux)) Max-Forwards: 1 Content-Type: application/json {"action":1,"aor":"marshal@org","ruid":"uloc-5a712c1a-1901-dae1","c":"sip:va-server@100.2.129.149:6060;ob","received":"sip:100.2.129.149:6060","path":"","callid":"R6m3zCogWsifTLebJ7n6zmlGHOwk1xA6","user_agent":"CallServer","instance":"","expires":1517473708,"cseq":5015,"flags":0,"cflags":0,"q":0,"last_modified":1517473678,"methods":8159,"reg_id":0,"server_id":0} -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
