Summary:                    Asterisk crashes sometimes, when using Mixmonitor
Description: 
Hello,

I am using Asterisk 1.4.18.1, Zaptel 1.4.8, Libpri 1.4.3, Addons 1.4.5.
It's a Call Center with 30 agents running X-lite.

I am recording all calls by using Mixmonitor.

Since I've started using Mixmonitor, Asterisk crashes and restarts itself,
at least twice a day.

Is there a patch to fix this, for Asterisk 1.4.18.1 ?

I don't want to upgrade to 1.4.19 or 1.4.20, at least in this moment,
because I am using AgentCallbacklogin.

Could please help me with this issue ?

Thanks.

Hello,

I'd like to report another issue related to Mixmonitor.

Since I have upgraded from Asterisk 1.4.17 to 1.4.18.1, I am observing
latency in recordings.

I get strange files , jittered, slowed and stuttering, no matter wav or
gsm format was used.

The problem seems to affect mainly outubound calls.

MixMonitor records one of the legs of the call 
with some 10-15 seconds of delay and/or the voice is very quite.

Records one leg of call faster than the other leg. It doesn't align the
recording, so one can hear smooth recorded conversation of both called and
calling party. 

It must be very easy to reproduce this issue, because it always happens.

In Asterisk 1.4.17 this problem doesn't occur.

That is part of my dialplan for outbound calls :

[local-dafra]

exten =>
_00800.,1,Set(MIXMONITOR_FILENAME=/dev/shm/saidas/${CALLERID(num)}-${CALLERID(dnid)}-${STRFTIME(${EPOCH},,%d%m%Y-%H%M%S)})
exten => _00800.,2,MixMonitor(${MIXMONITOR_FILENAME}.wav,b)
exten => _00800.,3,Dial(Dgv/g1/${EXTEN:1},90,tT)
exten => _00800.,4,Hangup()

exten =>
_01xx,1,Set(MIXMONITOR_FILENAME=/dev/shm/saidas/${CALLERID(num)}-${CALLERID(dnid)}-${STRFTIME(${EPOCH},,%d%m%Y-%H%M%S)})
exten => _01xx,2,MixMonitor(${MIXMONITOR_FILENAME}.wav,b)
exten => _01xx,3,Dial(Dgv/g1/${EXTEN:1},90,tT)
exten => _01xx,4,Hangup()

exten =>
_0[2-6]xxxxxxx,1,Set(MIXMONITOR_FILENAME=/dev/shm/saidas/${CALLERID(num)}-${CALLERID(dnid)}-${STRFTIME(${EPOCH},,%d%m%Y-%H%M%S)})
exten => _0[2-6]xxxxxxx,2,MixMonitor(${MIXMONITOR_FILENAME}.wav,b)
exten => _0[2-6]xxxxxxx,3,Dial(Dgv/g1/${EXTEN:1},90,tT)
exten => _0[2-6]xxxxxxx,4,Hangup()


Could you please help with this ?

Thanks.
