You should use STUN for communicating across Internet, so that the Contact address advertised in SUBSCRIBE does not use the private IP address. Also you should configure your server to record route SUBSCRIBE/NOTIFY sessions (if that's possible) so that the NOTIFY is sent via the proxy and not directly to the buddy, otherwise the NOTIFY will be dropped by the buddy's NAT router if it is address dependent filtering NAT (most NATs are, I think). cheers, -benny > How to resolve this problem? > Thanks!
