With this discovery, can we expect EuroISDN support for some form of call
transfer in the near future?

Obviously I can test.

It will not work for EuroISDN because pri_channel_bridge() does not have a
switch case to build the necessary messages.

I think the necessary messages are defined by ETSI 300-369-1 Explicit Call
Transfer (ECT).  LibPRI already knows how to encode/decode the ECT messages.
It does not have the code to know when or what to put in them.
