Campon

Repeatedly retry a busy extension after 30 sec with music-on-hold in between until that extension answers.

exten => 765,1,SetVar(CALLEDEXTEN=${EXTEN})
exten => 765,2,Dial(SIP/20,20,m)
exten => 765,3,Goto(campon,camp,1)
exten => 765,103,Goto(campon,camp,1)

[campon]
exten => camp,1,Answer
exten => camp,2,Wait(1)
exten => camp,3,Background(campon)
exten => camp,4,Background(silence/3)
exten => camp,5,WaitMusicOnHold(30)
exten => camp,6,Goto(default,${CALLEDEXTEN},1)

exten => 1,1,Wait(1)
exten => 1,2,VoiceMail(b${CALLEDEXTEN})
exten => 1,3,Hangup

Campon V2

This is a little more involved mini queue, the motivation behind this, is two fold:

1.) Small busy office where people arenࢀ™t disciplined to login/out of their phones, and one primary person to answer all calls unless they are not near their phone.
2.) After hunting 2 (or more, you can extend it) ext it will pass the call off to cell phones. In this case the call isnࢀ™t bridged to the cell unless the user acknowledges the call this prevents calls going to two voicemail systems.

When a call comes in it will be passed to the first ext, if the ext isnࢀ™t around/doesnࢀ™t answer then it will go to the next ext, in this case the first “extࢀ? is actually two simultaneous exts. If the first one is on another call, then the caller will camp on it until the line is free. For instance if you have a receptionist then she will get all calls if she is in the office, if not then they will passed to the next person.

Of course this will only work if you correctly set the group for outgoing calls as well.

Campon for busy outgoing.

Automatic redial
From https://www.cyber-cottage.eu/
Otherwise known as campon.

It can be usefull sometimes to have number redialed till free, As can be done by a “mobile phone”.

To this end I have created a simple addition to the dial plan to do this and play the correct tones when a call fails with a reason, This works with SIP IAX and ISDN trunks.

This is a new conf file called timeout.conf

;This file controls the action on timeout and invalid call handling
;
;
[timeout]
exten => s,1,Goto(s-${DIALSTATUS},1)  ; This gets the dial status
;
exten => s-NOANSWER,1,Playtones(congestion)
exten => s-NOANSWER,n,wait(10)
exten => s-NOANSWER,n,Hangup()
; 
exten => s-CHANUNAVAIL,1,Playtones(unobtainable)
exten => s-CHANUNAVAIL,n,wait(10)
exten => s-CHANUNAVAIL,n,Hangup()
; 
; If a destination is busy the call may press 5 and the call will be  queued
exten => s-BUSY,1,Playtones(busy)
exten => s-BUSY,n,Set(TIMEOUT(digit)=1)
;exten => s-BUSY,n,Set(TIMEOUT(response)=5)
exten => s-BUSY,n,WaitExten(5)
exten => s-BUSY,n,Set(redialtime=30)
exten => s-BUSY,n,Goto(s-CAMPON,1) ; If users press 5 the call is  requeuded
exten => s-BUSY,n,Hangup()
; 
exten => s-CAMPON,1,NooP(${redial})   ;This is the number dialed
exten => s-CAMPON,n,NooP(${cont})     ;This is the Context of the call
exten => s-CAMPON,n,NooP(${redialtime})
exten => s-CAMPON,n,waitmusiconhold(${redialtime})
exten => s-CAMPON,n,Dial(Local/${redial}@${cont})
;
exten => s-CONGESTION,1,Playtones(congestion)
exten => s-CONGESTION,n,wait(10)
exten => s-CONGESTION,n,Hangup()
;
exten => 5,1,Noop(${EXTEN}
exten => 5,n,Set(redialtime=15)
exten => 5,n,Goto(s-CAMPON,1) ; If users press 5 the call is requeuded
;
exten => _5.,1,Noop(${EXTEN}
exten => _5.,n,Set(redialtime=${MATH(0${EXTEN:1}+10)})
exten => _5.,n,Goto(s-CAMPON,1) ; If users press 5 the call is  requeuded
;
exten => i,1,Playtones(switching)
exten => i,n,wait(10)
exten => i,n,Hangup()
;
exten => t,1,Playtones(switching)
exten => t,n,wait(10)
exten => t,n,Hangup()

It is called from the extensions.conf in the following manner.

;Long distance context accessed through trunk
exten => _90~np~[1-2]~/np~XXXXXXXXX,1,Dial(${TRUNK1}/${EXTEN:${TRUNKMSD}})
exten => _90~np~[1-2]~/np~XXXXXXXXX,n,set(redial=${EXTEN})
exten => _90~np~[1-2]~/np~XXXXXXXXX,n,set(cont=${CONTEXT})
exten => _90~np~[1-2]~/np~XXXXXXXXX,n,Goto(timeout,s,1)

So you now dial out as normal and if you get busy tone you can either hold on and it will redial every 30 seconds or press 5 and it will redial every 15 seconds or press 5xx where xx is any number of seconds from 1 upwards and will redial 10seconds plus the number of seconds.

What will then happen is you will sit back and listen to MOH and it will redial at the defined time and you can wait or press 5 etc
