Abstract
An exemplary method provides access to call origination features contained in an internet protocol multimedia subsystem (IMS) for a subscriber of the IMS who originates a call request from customer premises equipment (CPE) outside of the IMS. The call request is received at a public service identity (PSI) server in the IMS with a phone number to which the call request is routed. An IMS internal desk number is retrieved based on the number of the outside CPE. A first modified call request is transmitted from the PSI server to a telephony application server (TAS) identifying the IMS internal desk number as a request universal resource identity (RURI). Call origination treatment as specified by the subscriber is performed by the TAS. The first modified call request is processed by the TAS to form a second modified call request in which the RURI is a number of a destination party and a P-asserted identity (PAID) is the IMS internal desk number such that the second modified call request appears as if it was initiated from a phone within the IMS. The second modified call request is transmitted to a node in the IMS for further processing and ultimately termination at the destination party.
