asterisk users - Apr 2010 - How to record a call in a single file when transfered...

I have a customer that needs to record all calls coming in and out.
The problem I am having is when a call comes in to the operator and it
is transferred to another extension.  The first mixmonitor begins
recording when the operator picks up but the recording stops when the
call is transferred.  I need to have a single recording  for the
complete call no matter how many times it is transferred.  Any tips?

See AUDIOHOOK_INHERIT() dialplan function.

	Thank you for that.  I am having trouble trying to implement this.
Since my macro-stdexten begins with:

exten => s,1,Mixmonitor(${UNIQUEID}.wav,b)

	I need some logic to prevent a name change of the file.  How can I know
if the call is already being recorded because it is a transfer or if I
need to start recording for a new call?  It seems that I cannot read the
value of ${AUDIOHOOK_INHERIT(MixMonitor)} to determine if it has already
been set so what other variable can I test?

You could set an inherited channel variable as the first thing you do before 
calling MixMonitor(). Something like:

exten => s,1,Verbose(2,Starting Call Recording)   ; I always start my first 
priority with something innocuous
exten => s,n,GotoIf($[${EXISTS(${CALL_RECORDED})}]?skip_rec_start)
exten => s,n,Set(__CALL_RECORDED=1)
exten => s,n,MixMonitor(${UNIQUEID}.wav,b)
exten => s,n(skip_rec_start),Verbose(2,Call recording already enabled)
exten => s,n,...


Something like that may work.

	Ok.  I got that working now.  The only inconvenience is that I cannot
use the h extension to rename and move the wav file to its final
destination but I am getting around that by running a cron job.  Thank
you very much.

	Another question if I may, with variable inheritance is it possible to
do something like: Set(__CDR(userfield)=${INITIALCID})?  That way I can
follow the call no matter where it is transferred to by having the
original outside callerid in the userfield.
