[Asterisk-Users] Overhead Paging

[Chris Albertson]

I'd hate to see conference bridging use for paging.  A lot of 
wasted CPU and bandwidth.  Could you "multicast" the UDP packets?

We assume you don't need to page across multiple Asterisk servers
but if you did the software wuld need to be smart enough to
"know" which groups of extensions could be in a multicast and
whci need to be bridged.  Basically check to see if the SIP phone
are on the same subnet.
