Hm. You did not get any response to the TCP connection request? What kind of SIP server you are trying to use? Sofia is supposed to implement the TCP switchover as specified by RFC 3261: If an element sends a request over TCP because of these message size constraints, and that request would have otherwise been sent over UDP, if the attempt to establish the connection generates either an ICMP Protocol Not Supported, or results in a TCP reset, the element SHOULD retry the request, using UDP. This is only to provide backwards compatibility with RFC 2543 compliant implementations that do not support TCP. It is anticipated that this behavior will be deprecated in a future revision of this specification. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
