I'm trying to address a problem with users transferring to invalid destinations.
In my sip peer I'm setting both __FORWARD_CONTEXT and __TRANSFER_CONTEXT to a context with a extension defined below to set some CDR variables before the call is transferred. [customer-forward] exten => _X.,1,Progress() exten => _X.,n,Gosub(do-billing,s,1${EXTEN})) exten => _X,n,Goto(customer-internal,${EXTEN},1) Now if my user Dials an invalid extension, Say '9595' from their sip phone they get back an 'Address Incomplete' message from their phone because it's not a valid extension defined in my dialplan. If my user Transfers a call to '9595' the call gets transferred and then hung up on as there's no '9595' destination. I'd like to reject the calls in my customer-foward context that do not exist in my customer-internal context. I've tried doing something like: exten => _X.,1,Progress() same => n,ExecIf($[${DIALPLAN_EXISTS(customer-internal,${EXTEN},1)} = 0]?Hangup(28)) But that's still accepting the call as the _X makes it a Valid extension. I'm looking for suggestions or ideas on a better way to do this. -- A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.
