Abstract
Abstract In a packetized communications system call waiting functionality is expanded to provide for handling of unlimited calls concurrently of one or more service types. When a subscriber is engaged in an ongoing call, incoming calls can be placed on a call queue by a call manager such that bandwidth and other resources are not allocated to a waiting call between the call manager and broadband residential gateway, and thereafter can be accessed by the subscriber in the order received or in the order desired by the subscriber. For subscribers with a device having video display capability, identification information regarding each call in the queue such as service type waiting time and caller identification information may be displayed at the subscriber's premises to allow the subscriber to manage their incoming calls. Also, a particularized tone may be heard to identify the incoming call including its service type.
