New to FreePBX/Asterisk - filtering/parking calls

Hi

I was trying to figure out how to filter anonymous calls, and found some info with this code for extensions_custom.conf:

[from-external-custom]
exten => s,1,Zapateller(answer,nocallerid)
exten => s,2,Wait(1)
exten => s,3,SetMusicOnHold(default)
exten => s,4,GotoIf($["${CALLERID(num)}" = ""]?who-r-u,s,1)
exten => s,5,GotoIf($["foo${CALLERID(num)}" = "foo"]?who-r-u,s,1)
exten => s,6,GotoIf($["${CALLERID(name):0:9}" = "Anonymous"]?who-r-u,s,1)
exten => s,7,GotoIf($["${CALLERID(name):0:7}" = "Unknown"]?who-r-u,s,1)
exten => s,8,GotoIf($["${CALLERID(num):0:7}" = "Private"]?who-r-u,s,1)
exten => s,9,GotoIf($["${CALLERID(name):0:7}" = "Private"]?who-r-u,s,1)
exten => s,10,GotoIf($["${CALLERID(num):0:10}" = "Restricted"]?who-r-u,s,1)
exten => s,11,GotoIf($["${CALLERID(num):0:4}" = "PSTN"]?who-r-u,s,1)
exten => s,12,Dial(Local/[email protected])
exten => s,13,Hangup

[who-r-u]
exten => s,1,Background(custom/no-caller-id-message)
exten => s,2,Wait(1)
exten => s,3,Record(/tmp/asterisk-stranger:wav,5,15)
exten => s,4,Background(custom/please-hold-connect)
exten => s,5,Goto(ext-park,70,1)
exten => s,6,VoiceMail([email protected])
exten => s,7,Playback(goodbye)
exten => s,8,Hangup

[ext-park]
exten => 70,1,Answer
exten => 70,2,SetMusicOnHold(default)
exten => 70,3,Set(CALLERID(num)=100)
exten => 70,4,Set(CALLERID(name)=Parked Call Info)
exten => 70,5,ParkAndAnnounce(silence/1:custom/anonymous-call-from:/tmp/asterisk-stranger:custom/to-accept-this-call-dial:PARKED:custom/otherwise-voicemail|40|local/[email protected]|who-r-u,s,6)
exten => 70,6,Playback(custom/otherwise-voicemail)
exten => 70,7,Hangup

Now, the recording of the anonymous callers name seems ok, and the call is put on hold… But I am never notified about the parked call in my ringgroup (600). The log says:

Any idea what could be the issue ?

First off this string is all sorts of wrong. You are using pipes (|) which have not been supported since 1.4. Everything must be a comma.

Secondly Park and announce only works with page groups. You’ve sent it “[email protected]” which is your ring group which is why it’s confused and not sure what to do

Yep, I also found out about the pipes - that has been fixed is most of the code…

Finally, after some tweaking, it looks like the setup finally works as expected…
