Hi

G711 (ULAW and ALAW) is usually the best choice as it is the best possible quality.

One usually compresses calls when bandwidth is more expensive than buying licences. If you do have to use compression, then g729 is the accepted choice, however, it is 10USD per concurrent license, or you can buy a transcoding card.

Here is a bandwidth calculator you may find useful in capacity planning.
