ABSTRACT:
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.
