Have a Google Pixel and as of this morning I am unable to call toll free numbers. When I dial the number I hear a rapid busy signal. I am able to call and connect to non-toll free numbers. I have restarted my phone and I have powered off my phone and restarted. Numbers that I have tried are: Soicial Security (800-772-1213) and DirectTV/ATT (877-407-4720, 888-388-6683) all have the same result. I was able to call these number last evening. Nothing has changed on my end. Same locatoin.
