Hi, I am using opensips 2.1 and I'm experiencing some weird behavior with SUBSCRIBE handling on an opensips server that is behaving as a SIP proxy. I also use the topology_hiding module to hide routing information from the clients.
The proxy receives an initial SUBSCRIBE from a device, the SUBSCRIBE
doesn't contain a "to tag" so I process it like a normal SUBSCRIBE message
and route it to the correct route which replies with a 200 OK with a "to
tag". Some time before the expiration of the SUBSCRIBE is passed I receive
a another SUBSCRIBE, this time with a "to tag" so my opensips config file
attempts to match it to a topology matching but for some reason it fails to
match it.
I have this configured:
modparam("dialog", "dlg_match_mode", 0)
Any idea why the second subscribe message is not being matched?
Attached is a capture of the initial and following subscribes.
Thanks,
Royee
