[Freeswitch-users] Shortest path to recording MP3

Hi, I have a DID and it is working with FS. What I would like is for some sort of recipe to: 1. Get the phone to pick up 2. Play a file 3. Record until a key is pressed 4. Playback the recorded file 5. Re-Record if they hit any key 6. If they hang up any time during step 3 or after, I want the file to be stored as an MP3 7. Once the file is converted, hit a URL indicating a new file is available for pulling down. I can figure most of this out probably, but am feeling a bit lazy - just bullet points on the most direct route would be good. This is a proof of concept project. Thanks! Christian
