You can send it in variosu way: a) Using SIP via INFO method (RFC 2976) b) Using RTP via RTP payload (RFC 2833) c) RTP inband (no please!) > 2) Does any one knows about an API that provides application developers to > add this functionality to the applications? Any SIP stack (and RTP) stack should implement RFC 2976 and RFC 2833. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
