Abstract:
A system and method are provided for implementing the Hunt group function without the necessity of using any proxy functionalities. The Hunt group function can be independent of the signaling protocol being used by VoIP terminals. Consequently, there is no need of any special or proprietary signaling protocol to be implemented. Instead of registering all members or all VoIP nodes belonging to a Hunt group to a registration entity, only one pre-configured VoIP node belonging to the particular Hunt group needs to be registered. Likewise, instead of all members or VoIP nodes in the Hunt group registering with a registration entity and having a Hunt group number in addition to their usual peer-to-peer numbers, only one pre-configured VoIP node in the Hunt group would perform the registration and be registered with the Hunt group number. All incoming calls to the Hunt group will be directed by the gateway to the pre-configured VoIP node first. A method of the present embodiment may be performed by the gateway to ensure that the incoming call is forwarded to a VoIP node within the Hunt group.
Abstract:
An apparatus includes a plurality of call controllers that are capable of establishing a plurality of communication sessions over a packet network using a plurality of signaling protocols. The apparatus also includes an application controller that is capable of supporting one or more supplementary services during each of the communication sessions. As particular examples, the application controller and at least one of the call controllers are capable of at least one of: placing at least one of the communication sessions on hold so a user may initiate another of the communication sessions, placing at least one of the communication sessions on hold so the user may accept another of the communication sessions, and establishing a conference using at least two of the communication sessions. The communication sessions may use a common signaling protocol or different signaling protocols.
Abstract:
A system and method is disclosed for implementing a multipoint control unit in an endpoint that is participating in and managing a multipoint audio conference in a packet network. The multipoint control unit establishes audio communications between a plurality of endpoints of the packet network, mixes audio communications from the plurality of endpoints, and provides echo cancellation for the endpoint that is managing the multipoint audio conference.

Abstract:
A method of improving voice quality in a packet based network. The method includes receiving an incoming call from a first endpoint and matching capabilities between the first endpoint and the second endpoint. The method also includes completing the incoming call if the capabilities match and tracking the packet loss associated with the network. The method also includes negotiating the voice quality based on the tracking and the capabilities. Also described is a devices and system for a similar method.
