Recording calls with Asterisk

Here’s how you can record calls to mp3 files with Asterisk.
Insert these to extensions.conf:
1 2 3 4 5 6 7 8 9 | [globals] MONITOR_EXEC=/usr/local/bin/asterisk-wav2mp3 [macro-record] exten => s,1,Set(CALLFILENAME=${STRFTIME(${EPOCH},,%Y%m%d%H%M%S)}-${MACRO_CONTEXT}-${DIALEDPEERNUMBER}) exten => s,n,Set(POSTFIX=$["${CALLFILENAME}" =~ "\/([0-9a-zA-Z#_\-]+)$"]) exten => s,n,Set(CALLFILENAME=$["${CALLFILENAME}" : "([0-9a-zA-Z#_\-]+)"]${IF($[${LEN(${POSTFIX})}=0]?: _${POSTFIX})}) exten => s,n,Monitor(wav,${CALLFILENAME},m) |
Recording start example:
exten => 555,1,Dial(SIP/1234,,M(record))
The script asterisk-wav2mp3 can be downloaded here. Make sure it’s runnable (chmod +x asterisk-wav2mp3). This script creates a stereo mp3 out of two mono wav files. You’ll need SOX and Lame encoder for this to work.

Hey Nonoo!
Thanks for the description! But my upgraded SOX not include mp3 codec and I can’t start converting wav record. How can I fix this issue?
Thx, Victor
Koszi a leirasert! A SOX nekem nem tartalmaz mp3 codecet es nem kezdi el atkonvertalni. Jelenleg van ket feloldalas wav fileom. Hogy tudnam kijavitani a SOX codecet? Mar a legfrisseb van fent.
Koszi, Victor
You have to recompile SOX from sources.
Still not working.
I figured out, Thanks!
