My One Talk app only drops calls given a very specific situation. I'm a property manager and receive calls via my Zillow property listings. Zillow provides a virtual number and routes calls to my One Talk number. When I connect with the call, while connected to WiFi, the call drops at 2-3 seconds, I'm not sure if this also happens will connected to LTE. I don't experience dropped calls in any other circumstance. Any thoughts on what's going wrong? Thanks, Mike
