Hi John, I´m very interested into this call forwarding capabilities and I solved this problem filtering on the web-script (in my case, php) the number the user can intert on the database. (I know it´s not an asterisk solution).

There is an issue that I couldn´t handle. When I forward the call, I want to charge the user that the call was made FOR. How are you dealing with that? Going direct to the point, I just need to know - a tip would be apreciated either - how to translate/replace the FROM field of the forwarded call.

Rgds, Ricardo.

I'm simply trying to forward calls to users who have the call forwarding feature enabled (FWD Status and FWD Ph Number kept in the astDB). The problem is that I want users to be able to forward calls to numbers that they would normally be allowed to dial within their own context. (I don't want a local call only person forwarding to a long dist number, for example.) I'm able to get the channel context for SIP devices but not for IAX or Zap Devices. I need some pointers on getting IAXPEER to work and how to handle getting the ZAP context info. If there's an easier way, I'm all ears. Thanks.

; #####################Set Some Variables####################
exten => s,1,Set(DEVICE=${ARG1}) ;i.e. SIP/johns_phone
exten => s,n,Set(Protocol=${CUT(DEVICE,/,1)}) ;Parse out SIP
exten => s,n,Set(Phone=${CUT(DEVICE,/,2)})  ;Parse out johns_phone

;Stuff omitted for some amout of brevity....

; #####################Make Forward Calls######################
; We only want people to be able to forward to numbers they could normally call ; We'll have to somehow get their dialing contexts from the channel conf files.
exten => s,n(Forward),NoOp()

exten => s,n,GotoIf($["${Protocol}" = "SIP"]?SIPDev)
exten => s,n,GotoIf($["${Protocol}" = "IAX2"]?IAXDev)
exten => s,n,Goto(ZapDev)

;ok, they are an IAX device so use IAXPEER
exten => s,n(IAXDev),Set(CalledUsersContext=${IAXPEER(${Phone}:context)})
exten => s,n,Goto(dial_time)

;ok, they are an SIP device so use SIPPEER
exten => s,n(SIPDev),Set(CalledUsersContext=${SIPPEER(${Phone}:context)})
exten => s,n,Goto(dial_time)

;ok, they are an Zap device so use... Uhhhhh.
exten => s,n(ZapDev),NoOp( I have no clue how to get the zap channel's context...)

exten => s,n(dial_time),NoOp(======================> Chan Type ${Protocol})
exten => s,n,NoOp(======================> Chan Name ${Phone})
exten => s,n,NoOp(======================> Channel User's context ${CalledUsersContext})
exten => s,n,Dial(Local/[EMAIL PROTECTED]/n)

IAXPEER() Seems to be broken or I don't know how to use it properly.
