Incoming Calls Go Directly to Voicemail while On Call
Hello! Recently when I am on an active phone call, if I receive an incoming call I am not prompted that this call is incoming nor am I notified. On the incoming caller's side, the call goes directly to voicemail and I am not notified in the Phone app of this missed call unless the caller leaves a voicemail.
Even then, in the recents tab of Phone there is no notification of a missed call.
I have Wifi Calling on and Do Not Disturb Off. These were the only two "solutions" I could find and this does not fix the issue.
This issue has been occurring for about 2 months now and I am completely updated on the most recent iOS 15.1
