So, I just tried to call Verizon @ 888-553-1555 via my Obi202/GV setup using and my keypresses weren't recognized. This is the first time calling an IVR line using this setup, so I can't tell if it is a limited issue or widespread. But, I was able to complete the call using Google Hangouts directly on my phone.
Anyone else with Verizon service with the same setup willing to call the number and see if they can navigate the IVR?
