Hmmm... I have tried to isolate this (I am a VoIP/Telecom technician with 20 years experience) and can only deduce it is a Verizon Network issue, several times a month I get or make a call and when the call is answered, one party usually seems to hear fine, the other party only hears a tiny blip of audio about every 1.5-2 seconds from the very start of the call until disconnect. I drove my son crazy for a about an hour tonight calling him a good 50+ times to make this occur, he is on Verizon in Minot, and I am in Bismarck, and both of us have impeccable voice and 4G signal (I can see the tower a 1/3 mile away from my kitchen window, he is on the 11th floor of an apartment building and is 2 blocks and eye-level with a VZW antenna array) and about every 5 to 10 calls, a bad one with the exact same symptoms. Very odd, everyone around here knows what I am talking about, but no one says they have every called VZW about the issue, saying stuff like "Cellular voice calls suck, that is just he way it is and always has been, they are not supposed to good quality or reliable" (do people really believe that?) and it has been going on for two years since I moved here. When I lived in Rochester, MN, it happened like a dozen times over a 4 year period that I can think of.
Guess I was just trying to get a feel for others if this is a wide-spread issue, or just a more localized one... anyone else have any input?
