I would imagine it's because they plan on doing all kinds of "neat" stuff with SIP including video, TXT, Windows Updates, who knows... SIP over UDP has some pretty serious packet fragmentation issues. If you end up with a large enough SDP or something that causes a SIP packet to grow larger than the smallest MTU in the path between your two endpoints it doesn't work (no fragmentation support with SIP over UDP). SIP over TCP does not have this problem. Also, you need SIP TCP support for TLS... -- Kristian Kielhofner _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
