 +# SIP Codec
 +
 +SIP codecs are [codecs](/​glossary/​c/​codec) designed for use with [SIP](/​glossary/​s/​sip) traffic.
 +
 +###  G.711ALaw
 +
 +G.711ALaw is a [companding](/​glossary/​c/​companding) standard using non-linear encoding and decoding to provide pulse code modulation mainly of voice frequencies with the A-law variant algorithm.
 +
 +###  G.711MuLaw
 +
 +G.711MuLaw is a [companding](/​glossary/​c/​companding) standard using non-linear encoding and decoding to provide pulse code modulation mainly of voice frequencies with the μ-law variant algorithm. It provides higher compression than A-Law, with higher distorion for smaller packets.
 +
 +###  G.729a
 +
 +G.729 is a compression standard with linear compression for voice with low bandwith requirements,​ suitable for [voip](/​glossary/​v/​voip) applications where bandwith conservation is an issue. It divides 10ms packets for a 8kbit/s transmission rate.
 +
 +###  G.726
 +
 +G.726 is a compression standard using [ADPCM](/​glossary/​a/​adpcm)to transmit voice at transmission rates of 16, 24, 32, and 40 kbit/s. The 32 kbit/s mode is the standard codec for [DECT](/​glossary/​d/​dect) wireless phone systems.
