My IT department requires the use of a Cisco gateway (VG series) for 3 new elevators we are installing. We recently installed a new Kone elevator, and the VG will not function with this car phone system (AT&T analog lines were installed).

Any suggestions for our new installs? We have a new Kone, Fraco and Thyssen Krupp elevator on their way.

AT&T lines are a very expensive option for us, and not the preferred solution.
