VOIP SIP-to-POTS...

As I was hacking around on a voice-over-internet-protocol endpoint, I got to thinking... Is a prop powerful enough to do VOIP?

On the hardware side, it would need:
  • An ethernet controller (like a ENC28J60)
  • some circuitry to drive the phone, ring the bell, etc. Would need to filter out the signal we are sending from the signal we are receiving...
On the software side, it would need:
  • A TCP+UDP IP stack
  • A SIP implementation
  • A RTP implementation
  • A web server for configuration (ideally)
This is all just kinda thinking out loud, but I think the propeller should be powerful enough to do everything. As far as codecs go, VOIP works fine with G711, which is just straight up PCM.

Once could even built it into a phone itself. Add an handset, an LCD screen, a ringer...

Just thinking out loud.

I never really thought about things like this and then realizing that I could actually build them. It's a nice feeling. [noparse]:)[/noparse]
