[OpenSIPS-Users] [Presence] How to receive presence NOTIFY over TCP ?

[Anca Vamanu]

Hi Pascal,

We found the problem - the socket on which the Subscribe was received 
was always used when sending the Notify.
Find attached a patch for tm module that should fix this problem. Please 
test and report the results.

Regards,
