Somewhat simple ethernet voice mail....

Hey all, new project just came down the line. Trying to figure out which way to go, and this forum has been superb for inventing or not re-inventing the wheel...

Here's the need:

A phone line connected device that can decode touch tones, play greetings, all via ethernet of course. Not sure, for cost, if it makes sense to have space on-board to store the greetings (audio) or if it can all be sent via ethernet on the fly. Maybe just remote, then all the audio and processing can be done via an ethernet connection to a running program on a PC (Mac of course).

First option, of course, is to not re-invent the wheel if anyone has seen something like this already.

Thoughts anyone?

Jeff

    There are chips for encoding and decoding telephone touch tones. Add the prop and an sd card to store and play greetings. There are also modules available to connect the prop to ethernet as well.

    Jeff -

    I don't fully understand the requirements of the device. The device you want to create connects to a phone line in the wall and to a phone, right? The device also connects to ethernet, right? Via the ethernet one is able to get touch-tone information for what is pressed or passed over the phone line. Via ethernet the user is also able to trigger audio playback. Is this on the right track?

    What is the interface over ethernet? Is it a web page the user logs into or a program on the PC which passes packets to the device for the control?

    You could get the Propeller Platform and the PropNET Module I created to experiment with the Propeller and ethernet via a WIZnet module. This is a good prototyping platform. http://forums.parallax.com/showthread.php?p=877210

    The NXP mbed should be able to do all that:

    Who do you insist on doing this? This is a Parallax forum.

    It's a nice elegant solution that is available off the shelf, with a high-speed USB interface to the PC. A solution using Parallax parts will need far more work and wouldn't have anything like the performance.
