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 two signaling apparatuses. Signaling data for establishing the voice call is received by an originating signaling apparatus, which generates a message encapsulates the signaling data in accordance with a common signaling protocol, and transmits the message to destination signaling apparatus. The message, in accordance with the common signaling protocol, includes a call identifier that uniquely identifies the voice within the packet-switching network, the network address of a signaling apparatus, and/or a connection descriptor for a coding unit.
