I am trying to use my M1203b fastrack modem for voice calls. I have read the documentation including the AT commands required for voice comm (VGT, VGR etc.) but no success. I think it is a hardware problem :-) in particular a problem with the way I'm conn
ecting the modem to a speaker.
The modem has a serial connection and a telephone cable attached to it. The cable terminates in a RJ11 connector. I tried to:
a)Plug it into a landline telephone. After I accepted the connection "ATA", I couldn't hear anything coming through the phone handset
b)Plug it into a "Telephone Recording Adapter". This adapter takes in a RJ11 plug and sends the signal to a speaker (which can be used for recording). (There's another cable, but not relevant to this discussion). Again I made a call, but there was no outp
ut from the speakers.
I guess I'm doing something wrong here. Can anyone see what the problem could be?
