Summary:                    Record audio channels gets out of sync
Description: 
When recording with mixmonitor, some record files channels gets out of
sync.
The scenario was:
- Medium call traffic: More than 60 and less than 120 concurrent calls.
- All calls are recorded
- Codec: Alaw
- Record File format: WAV GSM
- Processor load: Never more than 50%
- Asterisk Version: 1.6.2.10 (also happened in older versions, since
1.4.19)
- SO Debian 5.0.3 - 2.6.26-2-686

---------------------------------------------------------------------- 
i have a 8mb connection most of the time and run router network analysis
which doesn't show any bandwith issues - periodic testing shows i have full
bandwith and 700Kbps.  My ISP does not 'shape' 5060 traffic.   But as you
say it's dahdi traffic that's the issue via PSTN = i use a TDM400 card.  
Strangely that's in incoming calls only.   I did see an issue on the log
about audiohook issues with dahdi and audiohook for incoming calls =  for
an outgoing call am assuming there's no bridge =   but for an incoming
call, the dialplan takes the call and then transfers/bridges the call via a
'dial' command to the sip channel/extension/phone for that context. 

There's been alot a issues/changes recently over audiohooks.   Until I
wrote my previous update to dvossel's request for info, i've never looked
at the dates around when 'my' issue starts/stop mixmonitor working, and was
very surprised and cannot more than a co-incidence that it's been every 24
days.

I have the 19th in my diary !
