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.

Extending originating capabilities of a subscriber to devices in any telephony network

A system and method for processing electronic data and voice audio calls providing an interLATA (Local Access Transport Area) fast connect routing scheme that bypasses an interexchange carrier. An interLATA communication circuit is established between a first switch in a first LATA and a second switch in a second LATA. The step of routing a call from the first switch to the second switch is performed. The call is routed to an interexchange carrier if the interexchange carrier is not a subscriber to a fast connect service. The step of bypassing the interexchange carrier is performed if the interexchange carrier is a subscriber to the fast connect service. Upon determining that the interexchange carrier is a subscriber to the fast connect service, the call is directly routed from the first switch located in the first LATA to the second switch located in the second LATA without utilizing interexchange carrier trunks or switches.
