[SBE] Hybrid issues.

[Chris Tarr]

Curt-

I may be reading that wrong, but wouldn't you want "mics only" to feed
the hybrid?  Not sure what the "hybrid out" feed would do (except
maybe offer an option to send audio form the audition channel down the
line) but the only thing that should feed the hybrid on a regular
basis is the microphones.  While an echo is indicative of poor
cancellation, it seems like maybe the caller audio is getting fed back
down the line.
