A call forwarding system for an AIN telecommunications environment is provided in which a destination has changed from an old telephone number to a new telephone number. A calling party places a call which attempts to contact the destination by dialing the old telephone number. The call forwarding system includes a hub switch, and an old address switch with which the calling party connects to upon dialing the old telephone number. The old address switch, upon recognizing that the calling party has called a telephone number which has been changed, prefixes the old telephone number with a three digit code, and forwards the call, along with the prefixed old telephone number, to the hub switch. The hub switch recognizes the three digit code, and launches an AIN trigger to an AIN platform which determines the new telephone number and whether the destination has elected to pay for forwarding the call to the new telephone number. The AIN platform also determines whether the calling party has elected to pay for forwarding the call to the new telephone number when the destination has not elected to pay for forwarding the call. The AIN platform completes the call to a new telephone number switch if either the destination or the calling party has elected to pay for forwarding the call. If neither the destination nor calling party has elected to pay for call forwarding, the call is not forwarded and is handled by standard switch based intercept treatment.
