摘要：
A method for connecting a call in an IP telephony system is disclosed. A dialed unique identifier is routed to a network device. The network device determines whether the dialed unique identifier has been ported. If the dialed unique identifier has not been ported, the network device attempts to connect the call to the dialed unique identifier. If the dialed unique identifier has been ported, new routing information is sent from a database to the network device. The network device then attempts to connect the call using the new routing information.
