You'll probably want to test this yourself, but although you'd think G.711 
would hold up better, I've found G.729a actually seems to give better 
results.  I don't know whether it's because it's contending for less 
bandwidth, or what, but it does seem to sound clearer.

It's what we're using on the INOC-DBA network, and we've got hundreds of 
phones on the ends of satellite links in the Pacific, central Asia, and 
Africa.
