[asterisk-users] Asterisk 1.4 Call Recording

[Steve Johnson]

Here's what I would suggest. You should insert some NoOp() statements
and watch the CLI as you dial your 555 extension so that you can see
whether it's working or not.

Your example (which you mentioned you want to run under Asterisk 1.4):
> [test]
> exten => 555,1,SetVar(CALLFILENAME=outgoing/${TIMESTAMP:0:4}/${TIMESTAMP:4:2}/${TIMESTAMP}-${EXTEN})
> exten => 555,2,Monitor(wav,${CALLFILENAME},m)
> exten => 555,3,Dial(IAX2/ics.iax-trunk/${EXTEN})
> exten => 555,4,Hangup()

In Asterisk 1.4 (read the UPGRADE.txt file in the source directory):
- SetVar() has been replaced by Set()
- ${TIMESTAMP} no longer exists.
- (CALLERID usage has changed in 1.4 also).

so you first have to fix that stuff, with something like:


[test]
exten => 555,1,Set(DATETIME=${STRFTIME(${EPOCH},,%C%y-%m%d-%H%M)})
exten => 555,n,NoOp(DATETIME: ${DATETIME})
;
; Tweak the callfilename until you're happy with it...
; Note that the default recording directory is /var/spool/asterisk/monitor
exten => 555,n,Set(CALLFILENAME=${CALLERID(num)}-${DATETIME}-${EXTEN})
exten => 555,n,NoOp(CALLFILENAME: ${CALLFILENAME})
;
exten => s,n,Monitor(wav,${CALLFILENAME},b)
;
; Remove this next line after the determining that you have the filename right
; by checking the console progress...
exten => 555,n,Hangup()
;
exten => 555,n,Dial(IAX2/ics.iax-trunk/${EXTEN})
exten => 555,n,Hangup()


My script assumes that the monitor files are in the default directory,
so adjust it if necessary after you get the above working.  When you
run it, the .mp3 stereo files should be produced.

In a production environment, I'd imagine that you'd want to run the
combine.sh script periodically as a scheduled cron job.

Don't forget to follow the legal standards for call recording in your
jurisdiction (and be nice).

Have fun,
S.
