Please shed some light on this.
The problem is the following:
After the first re-SUBSCRIBE with "CSeq: 2002 SUBSCRIBE" it seems that the
client doesn't receive the 202 responses from the server, neither the NOTIFY.
Note that subsequent re-SUBSCRIBE's are *retransmissions* (same branch, same
CSeq...).
The problem is that the client doesn't receive the second NOTIFY sent by the
kamailio (with "CSeq: 2 NOTIFY") so it doesn't reply the 200 for the NOTIFY
and Kamailio ends the subscription dialog. However I don't see retransmissions
of the NOFIFY from Kamailio, very strange...
So I think you have some kind of network problem since the client doesn't
receive subsequent requests (NOTIFY) or responses (202 to re-SUBSCRIBE's).
Are you in a local wired LAN? Well, I see that the client and server are in
different subnets so I suspect there is a IP routing problem, or perhaps you
have a NAT router between both networks, I don't know.
