ROUTING CALLS IN A NETWORK

摘要

A method includes receiving a telephone number mapping query associated with a call. The method may also include generating routing information based on the query and forwarding the routing information to a control device. The routing information may indicate that processing associated with routing the call is to bypass a core portion of an Internet multimedia subsystem (IMS) when a calling party associated with the call does not invoke an IMS service, the called party associated with the call does not invoke an IMS service and the called party is not an IMS subscriber.
