An inexpensive alternative for call queuing is provided by queuing calls at an intelligent peripheral within an AIN telecommunication system. A call to the subscriber line is detected at a local switch supporting the subscriber line. If the subscriber line is busy, the call to the subscriber is queued in the intelligent peripheral.

A method of routing a telephone call from a Caller to a Subscriber telephone line in an Advanced Intelligent Network (AIN) equipped with Terminating Attempt Trigger (TAT) and Terminating Next Event List (NEL) functionality and having at least one Central Office Switch (COS) and a Service Control Point (SCP) in electrical communication with a plurality of Subscriber switches via a signalling method and system. The system includes an intelligent peripheral in electrical communication with the COS and the SCP and which is equipped with queuing functionality for each of the Subscribers and operative to place a call to the COS for receipt by a Subscriber having a call placed in queue in response to a determination that the Subscriber's line is idle.
