The FaceTime feature on iOS 12.1.4 software does not seem to allow people to add a participant to their one-to-one call, according to several reports on the MacRumors forum.
iOS 12.1.4 released in February 7 as an emergency for the massive intercepting privacy error in Group FaceTime that allows users to listen to others without their permission.

However, some people are unable to add a person to a one-to-one FaceTime call because the Add Person button is grayed out and inactive in this situation. Again, this seems to happen after the iOS 12.1.4 update has enabled the FaceTime group for customers.
MacRumors has more:
MacRumors forum user Bob-K persistently in his support calls with Apple, and finally told that the Add Person button did not work in that situation, was a known issue and that they did not know when it should resolved.
We were able to reproduce this problem, but it seems that this solution is not entirely reliable as a user reported that he could not consistently add people himself during a group call.
The good thing is, this is nothing like the buggy that had serious privacy implications. Apple Support is aware of this issue, so the company will fix it soon.
Nor could we render the problem ourselves . It is quite possible that this only affects a subset of FaceTime users on iOS 12.1.4. The update of iOS 12.2, which is currently beta tested, can fix the problem with Add Person in FaceTime when published commercially.
