US Patent:

6570869, May 27, 2003

Filed:

Sep 30, 1998

Appl. No.:

09/163312

Inventors:

Udaya Shankar - Danville CA
Andrew West - Leesburg VA
Douglas Shriver - Manassas VA
Fred R. Rednor - Arlington VA
David Auerbach - Resron VA
David Hughes - Mountain View CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 1264

US Classification:

370352, 370354

Abstract:

Communicating voice over a packet-switching network is implemented on a telecommunications network that includes the packet-switching network, two coding units coupled to the packet-switching network and to an originating node and a terminating node, respectively, and at least one signaling apparatus. The first of the two coding units is configured to extract signaling data associated with the voice call and transmit the signaling data and its network address to the signaling apparatus. Signaling data for establishing the voice call is received by the signaling apparatus, and a network address of the first coding unit in the packet-switching network is obtained. The second coding unit is controlled to establish a bearer channel with the first coding unit for carrying the voice data through the packet-switching network, based on the network address.
