Turn On Caller ID
Caller ID doesn’t work in all iPhones as it is subject to your mobile carriers. If Show My Caller ID option is turned off, you should toggle this on: Settings → Phone → Show My Caller ID → turn on the switch.
If this doesn’t work, you can turn off two other options: Call Forwarding and Call Waiting.
Normally, users tend to reboot their iPhones when nothing works. You can also try this option if above solutions fail to give you any result when call failed on iPhone.

After a couple of seconds, hold the same button for some time to turn your iPhone on.
