The Wavecom Fastrack Supreme is a very powerfull bit of kit, but this new user is finding it not able to do the most basic task of a modem - accept a call & connect to another modem, if that modem is not GSM.
I can dial into another wavecom GSM modem and I accept a call from another wavecom GSM modem. However although I can answer a call from a landline modem, the wavecom does not appear to send any answer tones and the two modems fail to connect.
I have previously (some years ago) had success with this with an earlier Wavecom product, so I’m sure that the product has probably advanced and now I need to enable/disable some setting via the AT interface.
My supplier suggests it may be down to my mobile network operator (Vodafone). How likely is this? Are there recommended network operators for landline to GSM connections?
