I'm reviewing a potential project for a client, where his device is inline with the telco tip/ring lines.
   
  Essentially is a speed dial/memory type where it takes the phone line when it goes the phone goes off hook and then returns it back to the telco line.
   
  So, he will want to have it pass Part 65 (thats telco...or is it 68?) and so there is the isolation issues, but he also wants to pull power from the telco line to run the micro and such.
   
  Now, we all know that Ma Bell hates it when something is attached to the telco line, other than her stuff.  So if a device is pulling power off the line, will it pass FCC or get dumped right away.
  
I want to squash his dreams right away rather than get down the road and then find its not going to pass.
