The CODEC which is used depends on a number of things. First the VSP has to support it, then your ATA and Voxalot.

Some VSPs only do G729, others accept more options.

Most refer to G711a and G711u as just that whilst Voxalot refer to them as ulawa and ulawu. The 'right' CODEC setup for you depends mostly on your equipment and VSP advertised capaibilty -- note that some VSPs require you to request particular CODECS be available for use with your account too.
