After running a socket listener on 192.168.0.31 on the OpenSIPS host:
$ socat TCP4-LISTEN:2310,bind=192.168.0.31,reuseaddr -
SUBSCRIBE sip:mylogin-os...@192.168.0.31:2310;transport=tls;line=2acy67zm

CSeq: 11 SUBSCRIBE

User-Agent: OpenSIPS (1.6.1-tls)
Max-Forwards: 70
Event: dialog;sla
Contact: <sip:prese...@name.host.tld>
Expires: 610
I'm trying to implement presence by using the presence,
presence_xml, pua, and pua_bla modules.
So it seems that one of these modules (see event dialog;sla) is
getting the contact from the locations table (in AAA on our server)
and ignoring the Received header.
OpenSIPS replies to messages from UACs such as INVITE and CANCEL
properly, and opens connections to the IP in Received. This problem
is limited to the SUBSCRIBES sent from one of the presence modules.
...but I'm still not sure how to fix the problem. Any ideas?
Greetings,
Brian
