This document describes the RTP payload format for Enhanced Variable Rate Codec (EVRC) Speech. The packet format supports various formats for different application scenarios. An bundled/interleaved format is included to reduce the effect of packet loss on Speech quality. A non-bundled format is also supported for conversational applications.
