Something to be aware of is that after the transfer, even though the physical B-channels from the PRI link are not being used, they are still counted towards your total B-channel capacity (this is the case with my provider anyway). For example, if you have 12 B-channels from your provider, after 6 transfers no B-channels will be available until one of the previously transferred calls clears.

Your blatant plagiarism answered my question perfectly. Another way of saying this, for those of us who are familiar with Centrex, is that this allows one to mimic the old "Centrex-transfer" where you flash and dial another number and the call gets transferred (or conference'd)...
Makes sense and I think this is a valuable feature to have. I will see about lending technical and/or financial support.
Thanks, MC

Can you give me a readers digest version of how TBCT works? It might be something that our company will use in the future...
Thanks, MC
Blatantly stealing out of an old explanation found on the net:
Network Facility Request - Two B Channel Transfer (TBCT) (Synchronous Mode) TBCT enables an ISDN PRI user to request the switch to connect together two independent calls on the user's interface. The two calls can be served by the same PRI trunk or by different PRI trunks. If the switch accepts the request, the user is released from the calls and the two calls are connected directly. Billing for the two original calls continues in the same manner as if the transfer had not occurred. As an option, TBCT also allows for transfer notification to the transferred users.
TBCT works only when all of the following conditions are met:
The user subscribes to TBCT (this feature is supported for the 5ESS and 4ESS protocols only).
The two calls are of compatible bearer capabilities.
At least one of the two calls is answered. If the other call is outgoing from the user, it may be either answered or alerting; if the other call is incoming to the user, it must be answered.
In other words, you can transfer calls or otherwise connect 2 off-net stations without having to tie up two B channels and bridge them together yourself.
