I have two thoughts.  First, what is the latency between Office B and your *
box at the colo?  What is the latency between office A and your * box?
Compare these two and see if there is any corrilation to the delay when
making a call from office B.  If so, then its unfortunetly your network
configuration (using wireless network).  I know this isn't very useful, but
hopefully its at least a start in some direction.

Another thing which is probably veeeery unlikely (but who knows)...maybe the
phones at office B are not setup with a digit map and they are having to
wait for the DTMF timeout to be reached before sending the call?  Silly, I
know.
