We have a customer who is experiencing a strange problem we haven't seen before. When she dials a number, the CO is recognizing double digits even though she only dialed a single digit. Ex. (703) 442-3500 might be recognized by Verizon as (703) 442-(2)350. Various digits are recognized twice regardless of how it's dialed (long tones vs. short tones). I experienced the same thing when I tried it. We swapped out the phone from the kitchen to a bedroom thinking that something may have gotten into the phone causing this behavior. The double dialing occurs non the less. It even happens when she dials a speed dial number. That is... the double digits are dialed when the switch does the dialing. Any clue on what may be causing this? She is 29,000 feet from the CO if that matters. I was thinking it might be a repeater issue or an issue at VZ's switch. We will be dispatching a tech to perform 30 dials from the NID to try and determine if it's inside our outside. Help!!!
