further testing as requested by jpeeler on IRC on Friday.
Tested with TE110P without echocan module.

It's feasible, that txgain can be other than 0.0, but still digital calls
shouldn't be affected.

in chan_dahdi.conf
txgain=-0.1 to txgain=0.1 Unrestricted digital calls setup and connect but
no  transfer data.

txgain of +/-0.2 or more, digital calls setup, but no data transfer.
