"Call Ended" only when calling a certain person.
Both my husband (iphone 5s) and I (iphone 5) have the same problem with only one contact ( we can make calls to anyone else without a problem). Anytime either of us try to call his best friend we get a call ended tone and the call never connects. We have to text him then he calls us back. This started happening about 3 weeks ago. We haven't changed anything, our friend does not have us blocked, we have tried resetting the network settings and doing a hard boot by holding down the home and power button until it restarts, tried deleting his contact and adding it back in and nothing has worked. I haven't been able to find any into on the 'call ended' problem with only one contact which is why I'm asking here. Our friend has an iphone 4 and only my husband and I have a problem when calling him, he can make and receive calls with no problem. Thank you for your help.
