[Asterisk-bsd] Increasing delay in Meetme with ztdummy

   3 seconds is a delay of about 150 voice frames. This shouldn't be
possible with the channel.c patch, but perhaps Asterisk 1.4.x has another
queue somewhere (dynamic jitter buffer??). I guess there could be some
queueing going on in MeetMe as well.
   I'm still using 1.2.x on all of our VoIP servers, so I can't really
confirm proper behavior on 1.4.x.

   That all looks fine. Is your server running NTP and is it synced
with a stable network clock? Also, just to confirm, you never have
this problem on calls between extensions (through Asterisk) when not
using MeetMe?
