#132505 - DTMF Responding to: ???'s previous message |
If I am to understand your requirements, you want the cpu to dial using dtmf a phone number and from there there is audio from another source (voice).
The first thing to resolve is the line interface. Effectively, you can get this from a standard telephone methinks. Next is the dtmf dialling - the MT8880 just generates and receives DTMF tones- it has no interest in voice. I have no idea of what a TEA1062 does. It should not be a problem using 'c' code to talk to the MT8880. |
