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

[Anca Vamanu]

Hi Pascal,

I have just tested myself - with a Subscribe sent on udp and contact 
with trasport=tcp and the Notify is sent over tcp.
I would suggest to run opensips in debug mode and paste the log messages 
when starting the processing for sending the Notify ( starting with 
"DBG:presence:build_dlg_t: CONTACT ").

Regards,
