The longer and more accurate answer is that it depends on what you're doing and what your goals are. If you need to be able to pierce firewalls and handle NAT easily, especially in areas where a government-controlled telephone monopoly might be hostile to VoIP, then IAX2 is for you. If, on the other hand, interoperability and choice of phones are what you need, then SIP is pretty much a no-brainer. Of course, nothing prevents you from using SIP for phones and IAX2 for backbone, either. Notably missing to this discussion are the MGCP and H.323 protocols, which probably aren't much use to you, unless you need to connect to certain VoIP providers who haven't yet upgraded their equipment to the 21st century. -- Tilghman _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
