      Hey Don,<br>
      <br>
      How are you?  I may be heading your way in the next month or so. 
      Have to meet with a guy in Eden Prairie, and stop off at my
      brother/sisterm-in-law's as well.<br>
      <br>
      Got a question for you - with TBCT, who pays for the call once it
      is transferred?  Still me as the owner of the trunk?<br>
      <br>
      Lets say I take a call that was dialled locally (caller believes
      this is "free"), and I do a TBCT to an international destination,
      and they stay on the line for ten minutes.  Who gets the bill?<br>
      <br>
      Cheers,<br>
      <br>
      j<br>

              It depends who your service provider is!<br>
              <br>
              Any PRI card can send the commands down the D-channel to
              set any caller ID you<br>
              like, but it's still up to the telco whether or not they
              will honour your<br>
              request.  I know the hard way that BT will only let you
              identify with a number<br>
              you're entitled to use.<br>
              <br>
              Also, remember if you have a call coming in on a PRI line
              and going out on<br>
              another PRI line, that's eating two of your thirty lines
