I signed up for my numbers through Verizon for a second line on my phone. A few days ago, the call quality was good. Starting yesterday, it cuts out constantly. Audio goes in and out and people I'm taking to say I'm cutting in and out. I thought it was my bluetooth headset because coincidently I started using a new headset yesterday. I switched back to using my Plantronics headset that has worked great for months. I had the same exact issue calling over my numbers with the Plantronics headset. I then made a call from the native app using the Plantronics headset and the call quality was perfect. I figured if anyone could do a second line app, it would be verizon. I figured wrong I guess. What can I do to fix call quality issues with my numbers?
