Hi, I have this situation: SIP-Agent 1 <---> Registrar <-----> SIP Agent 2 If i kill the connection (cut the network) between Registrar and SIP Agent 2, Agent 1 will not close the connection. If it possible to make a simple End - to End Keep Alive. I tryed REINVITE and UPDATE for Agent 1 but both will rebuild my media streams (not really good for the voice) regards Mark -------------- next part -------------- An HTML attachment was scrubbed...
