I am in a situation where I often need to change the active call flow control (which can only be one..right?). I find that netsting call flow controls is very unhandy if you have 4 different scenarios. So what I would like to do is to create an 4 different extensions that set the appropriate call flow as the inbound route destination.
To make an example: I have
I would like to create:
Is something like that possible? If so...how would you achieve it? My system is based asterisk 11 and freepbx 2.11. Thank you in advance for your time and effort.
I figured it out
edit /etc/asterisk/extensions_custom.com and paste the following
[from-internal-custom]
include => enable-switch
[check-active-switch]
exten => s,1,NoOp("This context loops through all the switches and checks which one is ON. Than it follows its destination")
exten => s,n,GoSub(sub-get-nr-of-switches,s,1)
exten => s,n,Set(nrofs=${GOSUB_RETVAL})
exten => s,n,Set(i=0)
exten => s,n,Set(default-dest=app-daynight,${switchnr},1)
exten => s,n,Set(switchnr="NULL")
exten => s,n,While($[$[${i} < ${nrofs}] & $[${switchnr} = "NULL"]])
exten => s,n,Set(switchnr=${IF($["${DB(DAYNIGHT/C${i})}" = "NIGHT"]?${i}:"NULL")})
exten => s,n,Set(i=$[${i} + 1])
exten => s,n,EndWhile
exten => s,n,GotoIf($[${switchnr}!="NULL"]?app-daynight,${switchnr},1:${default-dest})
exten => s,n,Hangup()
[sub-get-nr-of-switches]
exten => s,1,Set(nr_of_s=0)
exten => s,n,Set(exten_state="NOT_ACQUIRED")
exten => s,n,While($[${exten_state}!=0])
exten => s,n,Set(exten_state=$[${VALID_EXTEN(app-daynight,${nr_of_s},1)}])
exten => s,n,NoOp(Exten nr ${nr_of_s} of app-daynight is ${exten_state})
exten => s,n,Set(nr_of_s=${IF($[${exten_state}=1]?$[${nr_of_s}+1]:${nr_of_s})})
exten => s,n,EndWhile
exten => s,n,NoOp(${nr_of_s} switches found)
exten => s,n,Return(${nr_of_s})
[enable-switch]
exten =>_*20X,1,NoOp("Abilita Switch selezionato e disabilita altre")
same => n,GoSub(sub-get-nr-of-switches,s,1)
same => n,Set(nrofs=${GOSUB_RETVAL})
same => n,Set(switchtoactivate=${EXTEN:3})
same => n,NoOp(Activated Switch nr ${switchtoactivate})
same => n,Set(i=0)
same => n,While($[${i}<${nrofs}])
same => n,Set(DB(DAYNIGHT/C${i})=DAY)
same => n,Set(i=$[${i}+1])
same => n,EndWhile
same => n,Set(freepbx_toggle_dest=*28${switchtoactivate})
same => n,Goto(app-daynight-toggle,${freepbx_toggle_dest},1)
same => n,Hangup
Next go to freepbx and create a custom destination -> check-active-switch,s,1 and set it as destination of the inbound route
