Abstract
A method and system of supporting abbreviated dialing between phones include determining dialing by a first phone of an abbreviated number associated with a second phone. The first phone is in a circuit-switched network associated with a Centrex system and the second phone is in an Internet Protocol (IP) packet-switched network disassociated from the Centrex system. The phones in the circuit-switched network are associated with the Centrex system. The Centrex system supports abbreviated dialing between phones associated with the Centrex system. A routing number for a phone call from the first phone to the second phone is determined as a function of the abbreviated number. The routing number includes IP addressing sufficient to support routing of the phone call through the packet-switched network to the second phone such as if both phones were associated with the Centrex system.
