Telephone Call Processing Method and Apparatus

摘要

The invention provides methods and apparatus for processing telephone calls in a packet-based telephony service. A store of telephone party identifiers is maintained for multi-service users having access to the packet-based telephony service and an alternate telephony service. Incoming signalling information for telephone calls in the packet-based telephony service is monitored and outgoing signalling information may be altered with reference to the store. An alteration may involve replacing telephony party identification data associated with one telephony service for telephony party identification data associated with another telephony service. The invention allows a multi-service user to be consistently identified by other telephony users by a single telephony party identifier instead of one telephony party identifier for each service they subscribe to. Further, a multi-service user can be identified at the call destination by a single telephony party identifier, irrespective of which telephony service is used to make the call.
