[Solved] 
This was extremely annoying, took me a few weeks to sort this out. In the
end: it is NOT hardware related, just a configuration issue:
1) We had a 'txgain = -5.0' on the span involved. Any txgain other than
0.0 stops DIGITAL calls to work.
2) Also any 't' or 'T' needs to be avoided in the Dial command, obviously
the channels need to be brigded natively.
Both points do not matter with 1.4.19.1, but with any higher version both
things need to be configured properly to get DIGITAL calls through.

Feature request: Ignore those paramters with digital calls.
