Update:
Greg from East Coast Communication called me to say that Verizon did the vendor meet and testing today. Verizon did agree that they "own" the trouble. Audio is lost at the record tone as described in an earlier post. Verizon tech made a reference to "something in toll fraud" whatever that means. They are hoping to resolve it by Monday. I won't hold my breath. In the meantime, I had a client today some 40 miles west of that troublesome location, who has been experiencing the same trouble for the last few weeks. I will keep updating this thread until we have a positive resolution. If anyone out there experiences similar trouble please join in.
