    abstract =  {This document specifies a Real-Time Transport Protocol (RTP) payload format for the Global System for Mobile communications (GSM) Enhanced Full Rate (EFR) speech codec. The EFR speech codec RTP payload format specified in this document closely resembles the EFR speech codec RTP payload format defined in TS 101 318 'Using GSM Speech Codecs Within ITU-T Recommendation H.323'. It is designed specifically to optimally interoperate with existing (i.e., legacy) GSM circuit-switched transceiver equipment in the sense that it supports the following EFR speech codec circuit-switched domain functionality in the packet- switched domain: error concealment of lost speech frames and SIlence Descriptor (SID) frames. The EFR speech codec RTP payload format defined in TS 101 318 does not support this functionality. A MIME type registration for the EFR speech codec is also included.},
