#105828 - Chips?
Responding to: ???'s previous message

CML micro have a range of embedded modems.

Do they?
They do modem Chips, but I didn't know that they actually did modems (or modules).

eg, here's an 8051 and a modem on a single chip:

The thing with this is that'd you'd have to make your own line interface, and this is not a job for a novice!

Telephone line interfacing is a specialist area - there are many technical gotchas!, and it's also fraught with legal and regulatory issues.

Buy a module (or dev kit) with a ready-made and approved line interface!
