Codecs for Europe: a-law/alaw/malaw/g711a/711a and for USA: u-law/ulaw/mulaw/711u/g711u. Never use the “u” version.

Many phones have by default ulaw selected, this seriously degrades voice quality. As well it uses a large amount of CPU cycles.

g729a is a licensed codec with low bandwidth use. This is supported in the AOX but requires additional licensing.

Please contact us department if you have any further questions.
