Thus, what is the limitation?
TE = slave  ?????
NT = master ?????

Using spandsp and V-4BRI does not work?

What about a pass-through scenario:

PSTN <-2xBRI-> Asterisk <-2xBRI-> oldPBX

Does Asterisk with the V-4BRI allows to pass through fax calls (or other
data calls) from the PSTN to the old PBX?
