1. A method, comprising:
- monitoring a packet loss measure during a Voice over Internet Protocol (VoIP) communication between a first endpoint and a second endpoint, wherein the first endpoint and the second endpoint use a first CODEC to conduct the VoIP communication;
when the monitored packet loss measure exceeds a maximum packet loss threshold and when a current frames per packet value used by the first CODEC satisfies a maximum frames per packet threshold associated with the first CODEC, negotiating use of a substitute CODEC having a substitute nominal data rate that is lower than an in-use nominal data rate of the first CODEC; and
continuing the VoIP communication using the substitute CODEC.

Abstract
Systems and methods of Voice over Internet Protocol (VOIP) communication are provided. A particular system includes a VoIP endpoint. The VoIP endpoint is adapted to monitor a packet loss measure between the VoIP endpoint and a second VoIP endpoint during a VoIP communication using a first CODEC. The VoIP endpoint is also adapted to negotiate with the second VoIP endpoint to select a substitute CODEC having a nominal data rate that is lower than an in-use nominal data rate of the first CODEC.
