Dear Alex; Thanks for your kindly reply.
Please explain for me what do u mean exactly in "a la" in the following sentence u wrote it below? " in SIP, this can be done via "re-INVITEs" a la the canreinvite= option for SIP peers in sip.conf" Another thing, do u mean that it is easier (better) if we need H.323 endpoint to talk with SIP endpoint then we use full proxy (signaling + media) so that will solve miss compatibility issues? By the way: Asterisk allow H.323 to talk with SIP? Regards, ------------------- IP Telephony and Contact Center Engineer Eng. Bilal Ghayad Mobile: 00965 9849460 Bilal, Asterisk is an IP PBX and thus a back-to-back user agent; by default, it will proxy media. The only way to disengage it from the media stream is to use signaling protocol-specific mechanisms to coax the endpoints into talking to each other directly; in SIP, this can be done via "re-INVITEs" a la the canreinvite= option for SIP peers in sip.conf. The H.323 stack in Asterisk may or may not have a similar option, and it may or may not be compatible with SIP on a signaling level. That's if you're connecting one endpoint that's H.323 and one that's SIP. I imagine there's probably a way to do media stream handoff between two legs that are natively H.323 on both ends. But that's the determinant. Also, remember that even if you hand off the media, Asterisk still stays in the signaling path. This is all the more true if you're using it as a signaling gateway between heterogenous protocols. -- Alex -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : +1-678-954-0670 Direct : +1-678-954-0671 ____________________________________________________________________________________ Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more. http://mobile.yahoo.com/go?refer=1GNXIC _______________________________________________ --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
