Hi Benny, why don't you implement UDP Outbound? it has no mistery for the client, it just does the same as in case of TCP (adding ;ob to Contact URI for non-REGISTER and ;reg-id Contact header param for REGISTER). And then instead of sending double CRLF for NAT keep-alive, the SIP UDP client must send STUN Binding Requests (RFC 5389) to the SIP UDP port of the proxy/server. That's all :) PS: I've a SIP proxy implementing Outbound for SIP UDP/TCP/TLS clients. Ask me if you want to test. -- I?aki Baz Castillo <ibc at aliax.net>
