asterisk users - Jul 2011 - Mixmonitor concept's question

[RecordPrompts]

exten => 1111,1,Answer()
exten => 1111,n,NoOp(WelCome to conference section)
exten => 1111,n,Playback(ConfDemoWC)
exten =>
1111,n,MixMonitor(tmp/00Record/1111-${STRFTIME(${EPOCH},,%C%y%m%d%H%M%S)}.wav,ab)
exten => 1111,n,Konference(${EXTEN},ADRSV)

Hi

My basic doubt is that if 1 or more  person call 1111 extension then
recording will be started by asterisk Mixmonitor application.

So basic question will come into mind that all calls will start recording it
means more then 1 thread will start by asterisk for only recording purpose
but finally 1 file will be save at disk.

Am I right ?

Hi Virendra,

It has been my experience that if two or more calls happen in the same second 
(which is the least identifier you are using to make the file unique) then the 
result is that only one file is created. (the other(s) are not)

To solve that issue, you can use ${UNIQUEID}, something like:

exten => 6000,63,Set(CALLTIME=${STRFTIME(${EPOCH},,
%C%y%m%d%H%M%S)}_${UNIQUEID})
exten => 6000,64,Set(CALLFILENAME=6000-${CALLTIME})
exten => 6000,65,Set(CMD='/opt/lame/l.sh '${CALLFILENAME})
exten => 6000,66,MixMonitor(${CALLFILENAME}.wav|v(2)V(0)|${CMD})

Note that the 1st exten line wraps here in the email but it should be all on 
one line.
