In this path, you ideally just want the jitterbuffer turned off on both 
the * boxes [this should, in theory, happen automatically], and rely on 
the VoIP _endpoints_ to handle jitterbuffering and PLC.

I don't know how well the Grandstreams do this, but they probably have 
DSP code licensed to do this, etc.

The latest jitterbuffer patch tries to disable itself in this case 
(where you're bridged to another VoIP channel), but you can turn this 
off at compile-time This is all discussed in the mantis bug, BTW.
