Dear all,
I want to record stereo recording for all the calls in the Asterisk, two separate channels, meaning that callee and caller on a separate stereo channel in one stereo file, or two separate files each one channel in the same way, how can I do something like that ? Is it with MixMonitor ? Because whatever I am doing I could not get this done, any helpful suggestions of methods I can try?
Regards.
Yes, you use MixMonitor to do call recording. It has various options[1]. If something isn’t working, then you need to be more specific and show what you’ve attempted and describe what actually happens.
I have used this config for example, but it is terrible, and just records both channels in one file. I have placed in extensions_custom.conf:
exten => 101,1,Answer()
same => n,Set(CALLFILENAME=${CALLERID(num)}-${UNIQUEID})
same => n,MixMonitor(/var/spool/asterisk/monitor/${CALLFILENAME}-mix.wav,b,
r(/var/spool/asterisk/monitor/${CALLFILENAME}-in.wav),
t(/var/spool/asterisk/monitor/${CALLFILENAME}-out.wav),
V(2), v(-2))
same => n,Dial(SIP/user,30)
same => n,Hangup()

Yes.
You can use any (or all) of the following options to the MixMonitor
application:
r(file) - Use the specified file to record the receive audio feed. Like with the
basic filename argument, if an absolute path isn’t given, it will create the
file in the configured monitoring directory.
t(file) - Use the specified file to record the transmit audio feed. Like with the
basic filename argument, if an absolute path isn’t given, it will create the
file in the configured monitoring directory.
D - Interleave the audio coming from the channel and the audio coming to the
channel in the output audio as a dual channel stream, rather than mix it.

Which version of Asterisk are you using?

I have used actually the r and t option with D, there was little change, I just got two files that voice from both the caller and callee was recorded to in both files, I mean I got two files with r and t, but each file gain both the caller and callee in it.

There should not be any commas separating the options.

Never automate fully anything that does not have a manual override capability.
Never design anything that cannot work under degraded conditions in emergency.
