#132647 - external modem and voice? Responding to: ???'s previous message |
It is not clear to me how you will transmit voice on the line using an external modem and an RS-232 connection between modem and 805x.
Sending AT-commands should be no problem, but how to get your voice signal on the line without tampering with the modem line i/f? Afer all, using an external modem was suggested in order not to have any DIY stuff ditrectly connected to the phone-line... regards Patrick |
