I have a DELL Latitude CPx laptop with an ESS Maestro-3i sound card and a 3Com Megahertz 3CCM756 56K modem PC card. An external dual-jack PC headset (speaker and microphone, hands-free) is plugged into the sound card. The laptop is to be used to contact individuals in remote areas (with landline phone access, but no Internet or cellphone access).
Using the 3Com Speaker Phone utility that came with the modem, I am able to establish a voice connection over an analog phone line, but would like to do it without using the utility.
Can the voice connection be established using the laptop, as configured, just by issuing a series of AT Hayes commands. If it can, what is the command sequence? If not, how does Speaker Phone establish the call?
