Hi,
I am working on asterisk. I recorded a conversation using application command monitor. I started recording before dialling a number. The voice got recorded in two different files (voice in and voice out). Is it possible to record both the conversation in a single file? I tried to record after dialling giving monitor function the next priority to dial. But the conversation was not recorded. What else could be done?
I use Mixmonitor and it works well recording both sides of conversation, also you can adjust the volume of each. This is for 1.2 version.
exten => s,1,Monitor(wav,${CALLFILENAME},m)
"…when recording finishes, Asterisk will execute a unix program to combine the two sound files into a single sound file. By default, Asterisk will execute soxmix and then delete the original two sound files."
Therefore, use ‘m’ flag!
It works for me 
MixMonitor is the better solution because in and out audio files are mixed while the call is in progress, but I didn’t try it.
