Technical Examples

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 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.
