Re: [asterisk-users] SIP - Automatic Redial on No Answer
Here are the relevant parts from extensions.conf file. It works only for local
extensions whose number id 806xx. Note one thing: When you use the H extension
the generated CDR is wrong - the destination extension is H and not the
original number. I've done some small code change in Asterisk and has to file a
bug about it.
; regular local extensions:
; The flow is: If not available or no answer send to mailbox if exists,
; send busy if no mailbox. Same for busy.
; We try to avoid the n+101 rule whenever possible, but it is not always
; possible as HasVoiceMailbox() does only n+101 jump.
;;; First, save the caller and called numbers for *41 and *42 features.
exten = _806XX,1,Set(_To=${EXTEN}) ; Save the original extension dialled.
exten = _806XX,n,Set(_From=${CALLERID(num)}) ; Save the caller.
; Save the caller number at the called extension for *42 usage.
exten = _806XX,n,Set(DB(${To}/LastCaller)=${From})
; Where we called for *41
exten = _806XX,n,Set(DB(${From}/LastCalled)=${To})
; See whether this extension needs to ring at others as well. To define such
; an extension do inside the command prompt of Asterisk:
; database set EXT-NUMBER MoreLinesToRing SIP/firt-lineSIP/Second-line
exten = _806XX,n,Set(aEXTEN=${DB(${EXTEN}/MoreLinesToRing)})
; Now dial the extension.
exten = _806XX,n,Dial(SIP/${EXTEN}${aEXTEN},20,) ; Dial the phone for 20
seconds.
; No answer or busy
exten = _806XX,n,GoTo(s-${DIALSTATUS},1) ; Jump according to the failure
mode
exten = _806XX,n,Hangup() ; Just to be sure...
; No answer:
exten = s-NOANSWER,1,MailboxExists(${To}|j); Has a mailbox?
exten = s-NOANSWER,n,Busy(); No maibox = play busy.
exten = s-NOANSWER,102,VoiceMail(${To}|u) ; Has mailbox - send the call to
there
; Busy:
exten = s-BUSY,1,MailboxExists(${To}|j); Has a mailbox?
exten = s-BUSY,n,Busy(); No maibox = play busy.
exten = s-BUSY,102,VoiceMail(${To}|b) ; Has mailbox - send the call to there
; Congestion: Handle the same a busy.
exten = s-CONGESTION,1,MailboxExists(${To}|j); Has a mailbox?
exten = s-CONGESTION,n,Busy() ; No maibox = play busy.
exten = s-CONGESTION,102,VoiceMail(${To}|b) ; Has mailbox - send the call to
there
; Unavailable channel - act as busy:
exten = s-CHANUNAVAIL,1,Goto(s-BUSY,1);
; Called here when the call is successfull and the user hanged the phone.
; Check whether the user has a waiting callback queued on him/her
exten = h,1,NoOp(${From} ${To} ${EXTEN})
exten = h,2,Set(tmp=${DB(${From}/CallBack)}) ; Get who is waiting for us
exten = h,3,NoOp(${From} ${tmp})
exten = h,4,GotoIf($[ ${tmp} ]?5:103) ; Anyone waiting for us?
exten = h,5,DBdel(${From}/CallBack); And delete it...
; Create the callfile and then move it to the spool directory to make the call.
exten = h,6,System(echo Channel: SIP/${tmp} /tmp/test.tmp${To})
exten = h,7,System(echo WaitTime: 20 /tmp/test.tmp${To})
exten = h,8,System(echo Extension: ${From} /tmp/test.tmp${To})
exten = h,9,System(echo CallerID: Callback \\\${tmp}\\\
/tmp/test.tmp${To})
exten = h,10,System(mv /tmp/test.tmp${To} /var/spool/asterisk/outgoing/)
; No one is waiting for us...
exten = h,103,NoOp(Nothing to call)
; The activation codes for the above code.
; *42: Get the last number who called us, say it and call it.
exten = *42,1,Set(tmp=${DB(${CALLERID(num)}/LastCaller})
exten = *42,n,SayDigits(${tmp})
exten = *42,n,Goto(${tmp},1)
; *41: Camp on the last extension dialled
exten = *41,1,Set(tmp=${DB(${CALLERID(num)}/LastCalled)})
exten = *41,n,SayDigits(${tmp})
; Save it so when the other side hangs it will see it and dial us.
exten = *41,n,Set(DB(${tmp}/CallBack)=${CALLERID(num)})
exten = *41,n,Hangup()

Re: [asterisk-users] SIP - Automatic Redial on No Answer
Hi, It seems to perfectly match what I was after : - Alice calls Bob and Bob doesn't answer (busy ? not there ?). - Alice hangs up and dials something (*41 for instance). - Whenever Bob is hanging up a call (that would prove Bob is back and probably available), a call from Alice to Bob is triggered. Is *41 called a vertical service activation code like here ? http://www.voip-info.org/wiki/view/Asterisk+vertical+service+activation+codes Anyway, I would be very pleased to look at your code.

As always, there are many ways to handle this. If your phone supports SUBSCRIBE, Asterisk does it too. In that case, it's up to the phone. Otherwise, you could come up with a multiprotocol dialplan-based solution where you - answer A's call and play a prompt for busy or no reply - like in Voicemail - ask the user to press 1 to redial (if B is busy) - have an app monitor B's connection over manager - when B is done, place call to A, then connect to B - lock B so no one else calls in between The big issue here is the external app. Maybe someone can figure out a way to do it without it... /Olle --- * Olle E.

Re: [asterisk-users] SIP - Automatic Redial on No Answer
Hello, I've wrote a dialplan script which uses the H extension to do something similar to what you want. In general it uses the internal ASTDB for this: - When there is no answer (or busy) the caller hangs up, initiate a new call with some special code (*41 is used here by the public carrier, so I am using it also). Asterisk registers the data in its DB. - When the user disconnects the H extension is called. It then looks in ASTDB to see whether there is a user camoing on this extension. If so, a call file is created and Asterisk initiates the call. If this is what you need please tell me and I'll post the code on Thursday. I've already posted it in the past so you might search the archives in the meantime. __Yehavi: ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
