Abstract

A private branch exchange (PBX) or other communication system switch processes a call to determine if an identifier associated with the call has a corresponding entry in a stored list of external endpoints registered with the switch.
The switch directs the call to an external port of the switch for delivery to a given one of the external endpoints if the identifier associated with the call has a corresponding entry in the stored list of external endpoints registered with the switch. The given external endpoint does not have a fixed external port assignment in the switch. Instead, the switch dynamically selects from a set of external ports an available external port over which the call is directed to the given external endpoint. The dynamic selection of the available external port may be implemented using an automatic route selection (ARS) algorithm. The switch in an illustrative embodiment directs the call to an external port of the switch via a loop-back arrangement implemented between port cards of the switch, e.g., a loop-back trunk between an output port associated with a first port card of the switch and an input port associated with a second port card of the switch. Advantageously, the registered external endpoint is treated by the switch as if it were an internal extension serviced by the switch, such that desirable switch features may thereby be made available to the external endpoint.
