[Asterisk-Users] Syncronize Monitored Calls

[John Todd]

I expect the "falling out of sync" problems are due to lost packets 
in a VoIP stream, or some sort of missed IRQ or something on a Zap 
channel.  As noted several times, the muxing of the streams together 
is a nasty hack, and should be resolved by re-writing the Monitor 
application to handle those types of realtime clock audio outages.
