ABSTRACT:
Certain embodiments of the invention provides a method and system for 7-digit dialing in a 10-digit mandatory dialing area. Aspects of the invention may include collecting a dialed string of digits corresponding to a directory number for a dialed call and determining whether an area code should be pre-pended to the collected dialed string of digits. The area code may be transparently pre-pended to a 7-digit dialed directory number if it is determined that the call is for a local area in order to conform with mandatory 10-digit dialing. Otherwise, 10-digits may be collected and used to route the call.
