Dear Asterisk experts and users.
Let's assume I purchased the call number, let it be 2200
for simplicity. So when we call 2200, our call will be
processed with Asterisk, and come in, say, [incoming] context.
Well, then I'd like Asterisk to process all calls that a
*begin* with 2200, i.e. 2200101. My dialplan would include
something like:
  ;; extensions.conf
  [incoming]
  exten => _2200.,1,GoTo(incoming-2,${EXTEN},1)
  ; ...
  [incoming-2]
  exten => _2200.,1,NoOp(${EXTEN}) ; something I'd like to do
It does work with IP phones. But, if I purchase the DID #
2200, can I be sure that I will not lose the trailing
suffix? I mean if I type direct call 2200101, is it guaranteed
that in [incoming-2] context the correct full number 2200101
will be processed?
Thanks!
