'Codec' is a broad term for audio compression technology. MyNetFone uses codecs to package IP communications data so that it can be efficiently transmitted between phones.

MyNetFone uses the G.711a codec, it is the standard codec used in Australia and Europe. The G.711u codec is used within the US, and may be present in PBXs or UC platforms from US vendors. The G.729a codec is often used for conference calling services.

It can be important to know which codec is used for your VoIP service. It will affect how much bandwidth is used each time you make or receive a VoIP call.
