TUTORIAL Anonymous CallerID filtering for inbound calls

[Allen Ford]

I built from this example using Google text to speech and Google voice recognition. On top of that i cached the CallerID name so callers don't need add it twice.. and i have also included cell phone callers where callerID Name = CallerID Number. My full Dialplan shows here www.cyfordtechnologies.com

[who-r-u]
exten => s,1,agi(googletts.agi,"Hi Can i please get your name followed by the pound sign?",en)
exten => s,n(record),agi(speech-recog.agi,en-US)
exten => s,n,Verbose(1,Script returned: ${confidence} , ${utterance})
;Check the probability of a successful recognition:
exten => s,n(success),GotoIf($["${confidence}" > "0.4"]?playback:retry)
;Playback the text:
exten => s,n(playback),agi(googletts.agi,"Thank you ${utterance} i will save this for future calls",en)
; Cache CallerID
exten => s,n,System(echo "${CALLERID(num)}" "${utterance}" >> /etc/asterisk/callerID.conf)
exten => s,Set(CALLERID(name)="${utterance}")
exten => s,n,goto(from-ZoiperPush,${extenstion},29)
;Retry in case speech recognition wasn't successful:
exten => s,n(retry),agi(googletts.agi,"Can you please repeat more clearly?",en)
exten => s,n,goto(record)
exten => s,n(fail),agi(googletts.agi,"Failed to get speech data.",en)
exten => s,n(end),Hangup()

Hi, Allen Ford. THANKS! Not sure about your yum install and compile inside the dialplan. The dialplan only has asterisk user permissions so this may not fly. Probably need to add it separately as a prerequisite by logging in as root. All of these components are included in Incredible PBX builds, by the way.

Hi wardmundy
yes i compiled freepbx from source but i still get good info from this site , not sure if i shouldn't be posting


but yes it should run the command as root. it does on my machines, i asked in irc too and was told the core runs as root and passes asterisk commands as Astertisk user.. but i believe system commands would run as root.. when i run asterisk as safe with asterisk user, i get warning and errors. but commands do run as asterisk. but not when started normally.

Please test so i can know for sure if my box is not alone

Also the install will only take place if it doesn't find the googletts.agi file otherwise it skips it.

I'll give it a whirl. Thanks again, Allen Ford, and OF COURSE you should be posting! Come back often.
