[Asterisk-Users] IAX call traceability

[Velimir Novkovic]

Hello everyone!

On IAX topic.

Is there a way to know from which * box the call has originated and onto
which box the call is terminating before call terminates? Can the call
be trapped efficiently (from dial-plan or such) before leaving network
of * servers to PSTN (e.g. voice prompt "Your calling party is outside
of free-phone domain. Do you want to proceed?")

Suggestions, thoughts - appreciated.
