[asterisk-dev] Data Modem calls passthrough

[Anton]

I believe that 8bit-16bit-8bit (e1-slin-e1) convertion will 
break the data flow, please correct me if I'm wrong.

Though it's absolute requirement for some sort of 
applications... any panasonic PBX does it... Actually it 
was a shame for me when our tech dept asked why they cannot 
test DIALUP account over a new PBX I've installed, so I had 
to wire an additional direct line for them. 

Any way to make such a cheme working? What is needed for 
that?
