hi mike,
I just check A800, looks like the software is already the latest (P4-2-20).
the signalling is set to loop start already.
I see there is an option for modems call in configuration, I tried both setting (PSTN/PBX, Moip) but not working as well
I am not sure how to config A800 so that it can accept GSM modem’s call. This is the first time I ever use GSM modem to connect to A800..
