it's worth noting that we've had issues with meetme() suddenly turning 
into a complete noisy mess with 5 callers. this is on a Dual Xeon 64 
bit.. the meeting goes along fine with 5 SIP/IAX clients, then someone 
else makes a call (nothing to do with the meeting), and the whole thing 
falls in a heap.

this is using the ztdummy module compiled for Linux 2.6 timers, oh, and 
asterisk CVS HEAD.

I'm assuming it is something to do with timing and noise/echo, removing 
members one at a time will eventually clear up the conference.

we're trying out the app_conference instead to see if that solves the 
problem (at least it has libspeex's excellent noise canceling available, 
which should help)

Seeya,
