VG202 and FuelMaster

[junior.beatty]

Is anybody using FuelMaster with a VG202.  FuelMaster is a fleet fueling system which uses a modem for communication back to FuelMaster.  Per FuelMaster this requires an analog phone line.  Tried to use the VG202, but they say they can not connect.  I have called from my cellphone to the FuelMaster system and the modem does answer the call.  Initially their technician said it had to do with ring voltage, but since it does answer a call from my cell then I don't believe that is the problem.  It seems that they are using older technology, even though they just replaced the guts of our system with a new board and modem.  Hope somebody has worked with FuelMaster through a VG and can make some recommendations.

Hi

I think you need to enable Modem Passthrough Codec, which at times are not enabled (at least that has been my experience with VG224)

Could you please share your config?

This works with regular fax machines with no problem.
