Blind transfer

makko · April 29, 2006, 1:41pm

Hi,

I use FreePBX 2.0.1
When I make a blind transfert, I would like my call ring again my extension after a timeout, if the called extension does not pickup, even if the called extension has an active voicemail.

Thanks very much for help

After some corrections, here is the working code.

off the top of my head, that would take some custom work, don’t think you are going to get it with the standard dialplan. If you have a specific extension that you want to do this with, you could setup a queue with it to transfer the call to, which would loop back to you if they aren’t there. But otherwise, you’ll need to use something like call parking or do some custom work (I think).

At first, thanks for replie.

I solved my problem, and i think it could be an improvement of the basic extensions.conf of freepbx, as in this case, a blind transfer never cause a lost call.
So, the solution is pretty simple.
If it can be useful for someone, follows how I wrote this behaviour.
Just be indulgent, as I am an asterisk beginner, and my english is very bad!

At first, I add an macro in extensions.conf:

[code:1]
;make a blind transfer come back if the target is unreachable
[macro-comeback-blind-transfer]
exten => s,1,Cut(RETOUR=BLINDTRANSFER,/,2);On extrait dans RETOUR L’extension dÃÆÃÂ©barrassÃÆÃÂ©e de "SIP/"
exten => s,2,Cut(RETOUR=RETOUR,-,1);On extrait dans RETOUR l’extension dÃÆÃÂ©barrassÃÆÃÂ©e de l’ID de channel
exten => s,3,Ringing();//On fournit une sonnerie ÃÆÃÂ l’oreille de celui qui est en train d’attendre qu’on le ballade…
exten => s,4,Wait(10);//Attente pour permettre le raccochÃÆÃÂ© de celui qui a transfÃÆÃÂ©rÃÆÃÂ© sur les postes analogiques
exten => s,5,Goto(ext-local,${RETOUR},1);//On renvoie l’appel vers celui qui a tentÃÆÃÂ© le blind transfert…
[/code:1]

Second, I have changed the vm and exten-vm macros as follows

[code:1]
[macro-exten-vm]
exten => s,1,Macro(user-callerid)
exten => s,2,Set(FROMCONTEXT=exten-vm)
exten => s,3,Macro(record-enable,${ARG2},IN)
exten => s,4,Macro(dial,${RINGTIMER},${DIAL_OPTIONS},${ARG2})
exten => s,5,GotoIf($["${CHANNEL:0:5}" = “Local”]?s-${DIALSTATUS},1) ; if the channel is Local, then do not go to voicemail. This is primarily to avoid vm for call-forwarded extensions in ring groups
exten => s,6,GotoIf($["${ARG1}" = “novm”]?s-${DIALSTATUS},1) ; no voicemail in use for this extension
exten => s,7,NoOp(Sending to Voicemail box ${ARG2})
exten => s,8,Macro(vm,${ARG1},${DIALSTATUS})
;BEFORE
;exten => s-BUSY,1,NoOp(Extension is reporting BUSY and has no Voicemail)
;exten => s-BUSY,2,Busy()
;exten => s-BUSY,3,Wait(60)
;exten => s-BUSY,4,NoOp()
;AFTER
exten => s-BUSY,1,GotoIf($${LEN(${BLINDTRANSFER})} > 0?100) ;//Si on ÃÆÃÂ©tait issu d’un blind transfer, on jumpe en 100
exten => s-BUSY,2,NoOp(Extension is reporting BUSY and has no Voicemail)
exten => s-BUSY,3,Busy()
exten => s-BUSY,4,Wait(60)
exten => s-BUSY,5,NoOp()

exten => _s-.,1,Congestion()

;BEFORE
;[macro-vm]
;exten => s,1,Macro(user-callerid)
;exten => s,2,Goto(s-${ARG2},1)
;exten => s-BUSY,1,Macro(get-vmcontext,${ARG1})
;exten => s-BUSY,2,Voicemail(b${ARG1}@${VMCONTEXT}) ; Voicemail Busy message
;exten => s-BUSY,3,Hangup()
;exten => _s-.,1,Macro(get-vmcontext,${ARG1})
;exten => _s-.,2,Voicemail(u${ARG1}@${VMCONTEXT}) ; Voicemail Unavailable message
;exten => _s-.,3,Hangup()
;exten => o,1,Background(one-moment-please) ; si appui sur 0 pendant message boite vocale on arrive ici
;exten => o,2,GotoIf($[“foo${FROM_DID}” = “foo”]?from-pstn,s,1:from-pstn,${FROM_DID},1);on renvoie l’appel sur le standard
;exten => a,1,Macro(get-vmcontext,${ARG1})
;exten => a,2,VoiceMailMain(${ARG1}@${VMCONTEXT})
;exten => a,3,Hangup

;AFTER
[macro-vm]
exten => s,1,Macro(user-callerid)
exten => s,2,Goto(s-${ARG2},1)
exten => s-BUSY,1,GotoIf($${LEN(${BLINDTRANSFER})} > 0?100) ;//Si on ÃÆÃÂ©tait issu d’un blind transfer, on jumpe en 100
exten => s-BUSY,2,Macro(get-vmcontext,${ARG1})
exten => s-BUSY,3,Voicemail(b${ARG1}@${VMCONTEXT}) ; Voicemail Busy message
exten => s-BUSY,4,Hangup()
exten => s-BUSY,100,Macro(comeback-blind-transfer);//On renvoie l’appel ÃÆÃÂ celui qui a effectuÃÆÃÂ© le blind transfert

exten => _s-.,1,GotoIf($${LEN(${BLINDTRANSFER})} > 0?100) ;//Si on ÃÆÃÂ©tait issu d’un blind transfer, on jumpe en 100
exten => _s-.,2,Macro(get-vmcontext,${ARG1})
exten => _s-.,3,Voicemail(u${ARG1}@${VMCONTEXT}) ; Voicemail Unavailable message
exten => _s-.,4,Hangup()
exten => _s-.,100,Macro(comeback-blind-transfer);//On renvoie l’appel ÃÆÃÂ celui qui a effectuÃÆÃÂ© le blind transfert

exten => o,1,Background(one-moment-please) ; si appui sur 0 pendant message boite vocale on arrive ici
exten => o,2,GotoIf($[“foo${FROM_DID}” = “foo”]?from-pstn,s,1:from-pstn,${FROM_DID},1);on renvoie l’appel sur le standard
exten => a,1,Macro(get-vmcontext,${ARG1})
exten => a,2,VoiceMailMain(${ARG1}@${VMCONTEXT})
exten => a,3,Hangup
[/code:1]

Thats all!.
How does it works ?
When occurs a blind transfer, if the target is unreachable (busy, no response…) the call is back-forwarded to the “transferer”, no matter if the target as a voicemail or not.
A further direct tranfer to the target’s voice mail always being possible…
