I guess the same goes for accepting true multicast RTP. In any case, I'm at a new job and I'm thinking the Asterisk server may be a bit under-powered for paging a bit north of 100 users. This is more for day-to-day paging and not just emergencies, so it gets a bit more use, but right now I'm looking into this as something to do more than a pressing need, so maybe tweaks can be made elsewhere or hardware can/should be updated since we'll probably be sticking with the Asterisk-based solution unless I get really crazy and capture the packets the Polycoms are sending out for their paging feature and see if I can't implement that within Asterisk to have Polycom-compliant multicast.
