Not necessarily true here in the U.S.  Basically the feature you would
want is three way calling from your phone company.  I know with my
Verizon phone lines, after answering a call, if I hook-flash, I am
presented with another dialtone.  If I hook flash again, I have a
three-way call.  Basically, you could do this, but I am unsure of the
dialplan logic, although I don't think it would be totally difficult.
The difficult part would be to get * to hangup both legs of the call
after you are completed.

You should be able to accomplish this with either the TDM400P or the
X100P.
