Most of the major phone vendors (that are employed by the users of this list) have support for multi-cast of some sort. In recent firmware release notes I have read that SNOM has now also added a feature to feed multicast directly from a phone (and not just play multicast audio on the speaker as long as the phone is not in use). > I'm currently using some software I wrote which sends voice over > multicast RTP and coordinates all the sites with multicast messages. app_page has been around for quite some in Asterisk, and the new Asterisk 1.8 now also adds the channel driver "MulticastRTP". > Is there a way asterisk could be of use, or would I need to bend it > too much?
