I need to find a basic rs232 voice modem for a proof of concept device. The final product will have the functionality built in but for now I need an external solution.
The application will generate DTMF codes, and send a voice message. The modem needs basic hayes commands, enough to go off hook and dial out, send a message and hang up or hold the line open. ARM9 processor running a uLinux distro.
Any help would be appreciated.
