I'm guessing the handshake fails because the modems can't negotiate an 
appropriately high speed. Slow them down.

The tone you hear is called a guard tone, it's mainly used by Fax 
machines to tell the exchange equipment that yes, there really is 
something on the line.

Check the manual for the options of either:
  - not negotiating the highest speeds (start at 38kbps and work down)
  - only negotiating a known good speed (ie: 9600bps)

There should also be an option to turn off the guard tone, but that 
tone shouldn't be interfering with the modems' handshake.

Hope this helps
Alex
