Please, oh PLEASE, give us the phone number and name of the CC "tech" who told you about 24 V POTS lines. I wish to call him and have "an open and frank exchange of views" with him.
By definition, a POTS line is 48 volts. What instruments were you using, and what method of testing, pray tell, led you to deduce that you had a 28 volt POTS line?
And could you tell us how you came up with the name "George the phone guy?" I may want to get into abdominal surgery as a sideline, and I think "Arthur the doctor" sounds cool.
