BLU R1 HD | Will NOT ring

[plymouth2014]

Phone will NOT ring! Just goes to voicemail. All other sounds work. Do Not Disturb or Airplane is not enabled. Tried every fix I could find online. Volume is on Max, Uninstalled all apps, safe mode, factory reset, changed ringtones, reinserted SIM, etc.. Everything else works! Just won't ring on incoming calls. I've gotten it to ring on a few occasions after making changes but then it goes back to no ring after one time. Really don't want to give up or have to buy a new phone especially since everything else is working fine.
