  If you decide to try this, please use my code... I left the external mic, and headset mic option available; just comment out the one you don't want to use, by default its set to "HEADSET"... see description at the bottom of the "SETUP" section before the LOOP section.
  

  /* 
  does:
   * can make calls on the speaker & mic
  
  todo:
  
   * status notification updates in loop()
   * dim screen when no touches in 1 minute
   * receive calls
   * receive texts
   * candy crush

  I would like to see an Propeller Phone...
  
  I made a security system out of cell phone tech, because if the house power goes out, only cell phone tech will be active with battery backup...
  
  
  cheers...

  Sure, there are many apps for this already. An old Android phone can be put to good use, thanks to all the integrated features.
  
  Anyone can create an app, in minutes with RFO BASIC aka: BASIC! (with the exclamation). This is an interpreter that actually runs on the device.
  
  Makes a great front end for a microcontroller.
