Please help with super annoying issue

[Anonymous]

Hi please help... My son has an iPhone 5s and for some time now whenever anyone phones him the first time you phone it goes automatically to voice mail. The second time it rings. I have never had this issue with my android. However last week I moved onto an iPhone too( 6plus.) and low and behold the same is now happening to me! Just to clarify a few points so I don't waste anyone's time. We have full service full bars. Neither of us have the do not disturb enabled. We both have our phones set on silent.
The first time automatically to voicemail the second time it rings. Please help!!!!

Cs are shut. I have just phoned Apple and they advised I reset network settings. I'll see if that works and then take it from there . Thanks all

Hi everyone. Can I report back that resetting the network seemed to have sorted the problem for me. It hasn't happened since.
The apple helpline was amazing. Thanks everyone for your help x
