[cisco-voip] Changing called party number on inbound call?

[Erick Bergquist]

Well, if the called party number in the q931 is 4 digts, then that is
what telco sending. You or call manager has no control of what telco
sends. They can send 4 digits, 5 digits, 10 digits, all depends on how
the PRI is provisioned and such. As far as calling a different number
and the call coming in with other digits that aren't part of that
number, it sounds as if the number you have is mapped to another #
assigned to your PRI by a telephone carrier. Was this a older number
you had routed to another circuit at one point?   You should be able
to contact the telephone company your paying  for that number to see
what it is mapped to.
