Not recieveing incoming calls go straight to voicemail

When your iPhone is locked (the screen is off), Do Not Disturb silences all incoming calls, text message notifications, and alerts on your iPhone. Unlike silent mode, Do Not Disturb sends incoming calls straight to voicemail.

try transferring the calls from ur mobile to the voicemail when u r not available....
in call settings u might have an option of forwarding the incoming call after so many particular number of rings... forward the calls to ur voicemail numbers using this and then u ll have the numbers in ur recieved calls list.
this might work but is only a temporary solution

Sorry to hear you are having issues with incoming calls. You do wanna try a few tests. Check to make sre there's signal on your phone. There are no coverage issues. Do a powercycle, by powering the device down for about 10-30 seconds. If you have another phone with the same carrier, put your simcard in that phone. Do a test call. If it goes thru, it's software issue. If it fails, and goes straight to voicemail, then it's a network issue. Contact your carrier ASAP to get it resolved. If it's happens to be the phone. View the manual how to set the call forwarding. If that is set to be ringing and not straight to voicemail. Try a soft ware reset aka Master Reset. Your manual of this particular phone will be in there. You won't lose our number, pictures, message, etc. You'll see the phone will have the original ringtone and wall paper as if you just got it out of the box.

Cheers!

I believe this has to be done from your carrier.

check in settings/phone to see if you have maybe turned on call forwarding and it is being forwarded automatic to your voicemail box number
