making a modem a telephone device
I am developing a multimedia application with which i want to make a telephone application via a infokiosk. So, i want from the multimedia application to call a program(propably in c) which will make a call to a telephone.
I thougth that i could use a modem to make the call and have a telephone device cooperating with the modem. So i want to create a program which will accept a number, to dial the number and then not to send data as the modem usually does but to pass the voice to the telephone device.
Is it possible?
Can i do it with c?
Do you know from where i could start?
PS. Have u ever seen something similar?
