Is there some way to specify the use of a different codec (in this case, g.711 vs. g.729) for use with meetme? We have found that in the meetme case, with the necessity of decompression and recompression, it's worth it to us to use g.711 (use the bandwidth and save the processor) as opposed to the general case where g.729 outperforms.

MeetMe doesn't use G.711, it uses signed linear (well, this really happens in the Zaptel code that does the audio mixing, but the result is the same). -- Kevin P.
