It's only *remotely* possible if everything's G.711 all the way
through, I think.  If there are any analog transitions in the middle
(and possibly even if there aren't) you won't get anything over
33k6bps, and probably less than that.

*Any* phase non-coherence will break anything faster than 202/212, I'm
pretty sure.
