Russ, that makes sense.  And if the modem came with its own dialer package,
might he be able to get it to work with Outlook?  Or if the dialer hands off
to the modem card and it has SP capabilities then he should be able to talk
after dialing from his contact??  The next trick would be getting his
earphone drivers to work with the modem and its audio drivers.

I realize this is all very "maybe".
I apologize for misinterpreting your answer.  You're correct in that it
isn't an Outlook issue because if Outlook does the handoff it has pretty
much completed its job.  I wouldn't have known where to send him either
because all to often tech support for equipment isn't up to par and
comparing their pay to yours (;- they are infinitely overpaid.  Just had
multiple experiences of that and the only answer is to throw in the towel or
use much patience with a lot of perseverance.  Almost a month wasted but I
seem to be back up.

And to the questioner if you are following along still.  Check your modem
capabilities first and maybe their support.  Try a hook up with a phone
first as I mentioned earlier.  If that works, maybe then you can get the
drivers for your Bluetooth audio device to work with the modem.  Good luck.
You are probably traveling in uncharted waters and could run into conflicts.
