Abstract
A communication device is coupled to a packet network and includes two ports coupled to two analog telephones. The communication device receives a message from the packet network indicating a called number and processes the called number to select one of the ports and to transfer a ring signal through the selected port to ring the analog telephone. The communication device transfers a message to the packet network indicating that a called party is being alerted, detects an off-hook condition for the analog telephone and stops the transfer of the ring signal, transfers a message to the packet network indicating packet routing information for the communication session, exchanges analog voice signals with the analog telephone through the selected port, exchanges voice packets with the packet network using the packet routing information, and interworks between the analog voice signals and the voice packets.
