ABSTRACT:
A system for changing the coder-decoder utilized during a voice over Internet protocol telephone call is disclosed. The system includes two local area networks connected to each other via a wide area network. Each local area network includes a router connected to the wide area network, a switch connected to the router and a voice over Internet protocol telephone connected to the switch. The voice over Internet protocol telephones are configured to detect when voice packets are being dropped and utilize a lower bandwidth coder-decoder.
