[Asterisk-Users] g711 ulaw vs alaw

[Whisker, Peter]

Partly is is down to the fact that G.711u (mu-law) is primarily used in the
USA and G.711a (a-law) is used in Europe.

Like you, I am not sure if the exact differences - they have the same
bitrate and audio, although there are minor differences in the format.

Hi All,

Can someone explain to me the difference between g711's ulaw and alaw
codecs? Is it just different header info or is the actual payload in
each encoded differently? I have thus far noe been able to find any
difinative  information onthe matter. All I've managed to find out
that they are "similar", they sound the same and that it doesn't
matter which you use. Could someone knowledgable please enlightmen me?
