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.
 
Ross
