Hi,

I would like to know if kamailio implements draft sip-outbound? Can i use draft sip-outbound? http://tools.ietf.org/html/draft-ietf-sip-outbound-15

It doesn't implement it. But it does implement the PingPong TCP keepalive method described in outbound draft, this is: the UA sends periodically a double CRLF after registering and the registrar replies a single CRLF. This mantains open the TCP connection even behind NAT.
