IPhone not always ringing, going to Voicemail
iPhone 12 Pro Max. It doesn’t ring. My watch does. Verizon tech has reset connection, and it worked for about 30 minutes then quit. Next tech had me turn off WiFi calling, I also have a network extender on. Verizon 4 bars and WiFi 3. The ringer is on, DND Is off, just on scheduled, airplane mode off, sound on. I did have Verizon’s Call Filter on and disabled it, although the caller is in my contacts. The calls ring twice and go to Voicemail ( I don’t hear this, the caller does) . Any suggestions? Thanks.
