How to make FreePBX record the two legs of a conversation separately and pass the files to nTRAC for further processing.
To automatically transcribe all on-demand recordings (recordings that you initiate by dialing *1 during a call), paste the following into the file /etc/asterisk/extensions_override_freepbx.conf:
[macro-one-touch-record]
include => macro-one-touch-record-custom
exten => s,1,Set(ONETOUCH_REC_SCRIPT_STATUS=)
exten => s,n,Set(MONITOR_EXEC_ARGS=--google --en_US)
exten => s,n,System(${AMPBIN}/one_touch_record.php "${CHANNEL(name)}")
exten => s,n,Noop(ONETOUCH_REC_SCRIPT_STATUS: [${ONETOUCH_REC_SCRIPT_STATUS}])
exten => s,n,Noop(REC_STATUS: [${REC_STATUS}])
exten => s,n,GotoIf($["${ONETOUCH_REC_SCRIPT_STATUS:0:6}"="DENIED"]?denied)
exten => s,n,ExecIf($["${REC_STATUS}"="STOPPED"]?Playback(beep&beep))
exten => s,n,GotoIf($["${REC_STATUS}"="STOPPED"]?end)
exten => s,n,GotoIf($["${REC_STATUS}"="RECORDING"]?startrec)
exten => s,n(startrec),Monitor(sln16,${MIXMON_DIR}${YEAR}/${MONTH}/${DAY}/${CALLFILENAME},m)
exten => s,n,ExecIf($["${REC_STATUS}"="RECORDING"]?Playback(beep))
exten => s,n(denied),ExecIf($["${ONETOUCH_REC_SCRIPT_STATUS:0:6}"="DENIED"]?Playback(access-denied))
exten => s,n(end),MacroExit()
;--== end of [macro-one-touch-record] ==--;
In line 4, you can modify or add the parameters to your liking. Or, delete the line and use the defaults set in ntrac.config. The three files (channel 1, channel 2, output) will be passed to the script automatically.
Next, edit the file /etc/asterisk/globals_custom.conf and add the line:
MONITOR_EXEC=/usr/local/bin/ntrac
Lastly, issue the command fwconsole restart to make the system aware of your changes.
Tested with Incredible PBX 13-13 and 16-15 on CentOS
