[OpenSER-Users] OpenSER Proxy & Presence Server - sr-users

21 Jun 2008


      Hi,
I have a working OpenSER Proxy to asterisk and would like the proxy server to handle Presence.
I have tried adding all of the usual presence code, however it seams that messages are not getting back to the clients. I can see time outs in the SIP messages.
Can anyone see what has gone wrong with this code?
The setup is:
Calls & Registrations:
Client --> OpenSER --> Asterisk
SIP Messages & Presence:
Client --> OpenSER
Thank you for your help in advance.
