Although in a bugtracker posting with a patch from over two years ago,
Matt Fredrickson from Digium says that it works with 5ESS under
Asterisk 1.2.X:

There are also bounties and claims of this feature working on NI2
protocol(although no patches posted) on the voip-info.org Wiki:

http://www.voip-info.org/wiki/index.php?page=Asterisk%20bounty%20PRI%202B%20channel%20transfer
As for actually using this feature, you apparently need to add the
following lines to the zapata.conf section that you want to be able to
use 2BCT:
facilityenable = yes
transfer=yes
To execute the transfer, you need to use the "Transfer" cmd within
Asterisk:

And according to this post, you can only do 2BCT transfers if the
first call is inbound:

Does 2BCT work with DMS100 and 5ESS right now?
Are there people using this in production right now that can shed some
more light on exactly how they are using it, and executing the
transfers?
Any input would be greatly appreciated.
Thanks,
