Abstract

See full text

A method and an apparatus for processing a call to an aggregate endpoint device over a network are disclosed. For example, the method receives a session request by an application server, wherein a route header for the session request comprises an aggregate endpoint identifier, and determines at least one Public User Identity (PUID) of the aggregate endpoint device in accordance with the aggregate endpoint identifier. The method obtains a Serving-Call Session Control Function Fully Qualified Domain Name (S-CSCF FDQN) of a Serving-Call Session Control Function (S-CSCF) that performs a termination processing for the aggregate endpoint device, and forwards the session request to the S-CSCF with a route header that comprises the PUID of the aggregate endpoint device.
