[Asterisk-Users] Calls forwarding to numbers only in user's context

[Bartosz Piec]

Hello,

I'm trying to do call forwarding based on this: 
http://www.voip-info.org/wiki/view/Asterisk+call+forwarding

In the extensions.conf file I have several context defined (local, 
longdistance, mobile, international and so on). Each user can be 
associated with different context (so can make only i.e. local calls). 
How to set calls forwarding only to numbers that are available in user's 
context (so if he has only locals calls he cannot set calls forwarding 
for mobile phones)?

I'm using this for forwarding:

[forwarding] ; available for all users
; Unconditional Call Forward
exten => _*21*X.,1,DBput(CFIM/${CALLERIDNUM}=${EXTEN:4})
exten => _*21*X.,2,Background(auth-thankyou)
exten => _*21*X.,3,Hangup
exten => #21#,1,DBdel(CFIM/${CALLERIDNUM})
exten => #21#,2,Background(auth-thankyou)
exten => #21#,3,Hangup

; Call Forward on Busy or Unavailable
exten => _*61*X.,1,DBput(CFBS/${CALLERIDNUM}=${EXTEN:4})
exten => _*61*X.,2,Background(auth-thankyou)
exten => _*61*X.,3,Hangup
exten => #61#,1,DBdel(CFBS/${CALLERIDNUM})
exten => #61#,2,Background(auth-thankyou)
exten => #61#,3,Hangup

[macro-call-forwarding]
exten => s,1,Set(temp=${DB(CFIM/${ARG1})})
exten => s,n,GotoIf(${temp}?cfim:nocfim)
exten => s,n(cfim),Dial(SIP/${temp}@ruter)   ; Unconditional forward
exten => s,n(nocfim),NoOp

exten => s,n,Dial(SIP/${ARG1},20,tTwW)

exten => s,n,Set(temp=${DB(CFBS/${ARG1})})
exten => s,n,GotoIf(${temp}?cfbs:nocfbs)
exten => s,n(cfbs),Dial(SIP/${temp}@ruter) ; Forward on busy or unavailable
exten => s,n(nocfbs),Goto(s-${DIALSTATUS},1) ; 
NOANSWER,BUSY,CHANUNAVAIL,CONGESTION,ANSWER

...

[incoming]
;
; Incoming calls.
;

exten => XXXXXYY,1,Macro(call-forwarding,YY)
