Are you positive that your carrier PRI circuit has this feature enabled?

If so, how much are they charging you for this service?(if they are
not charging you for it monthly it is most likely not enabled)

What kind of PRI do you have? (5ESS, NI2, DMS100,...)

How many PRIs and trunk groups set up across them do you have?

I have set up 2BCT for two different call center clients before, and
neither implementation went smoothly as far as the carrier's part of
it was concerned. Asterisk and zaptel(Dahdi) can handle it and will
always attempt to do 2BCT on ALL native bridging of channels on the
same trunk group if you have Transfer=yes in zapata.conf(or the Dahdi
equivelent file). I have never configured 2BCT on an Asterisk 1.6
system, only 1.2 and 1.4 (using zaptel 1.4 for both), although I can't
see any reason why it wouldn't work.
