Abstract: A local area network includes a number of IP capable phones which send and receive packets of audio or other information to each other over the network. Some of the phones can be wired to the network and some of the phones can be wirelessly connected to the network. The network also includes one or more access points that serve as the interface between the network and the wireless phones and the network can include some sort of switching device, such as a router. In the event that one of the phones sends a packet of audio information to another phone and the packet is marked with an incorrect timestamp value, the phone receiving the incorrectly timestamped packet is able to correct the timestamp value so that the phone can process the packet of audio information.
