Group Facetime Camera won't work

You need an iPhone 6s or later in order for the video to work. If you have an older phone then it only works with audio.

Same with the filters, which only work with iPhone 7 and later:

My sister and cousin has the 5SE phone and their FaceTime group chat works. My son has the 6s and my other cousin has the 6plus and they both can’t see anyone in a FaceTime group chat but we can only hear them talk. Why is that? It’s newer than the 5SE.

This is not true. I have relatives that have the 5SE and their phone work with the Group FaceTime. I have my son and another cousin that has the 6plus and 6s and their Group FaceTime don’t work. We can only hear them talk and can’t see their faces. The camera is off and grayed out. Is there a fix for this?

It is an unless post, it does not answer question of the post and does not help to fix the problem. I do have iPhone 7 and i cannot even start the group call on FaceTime, since at the moment when I type in second participant the address list and the buttons for audio and video call become grey and inactive. Same time I can do the FaceTime Group Call form iMessages form iPhone and from MacBook Pro, but not form FaceTime native app on either of them. What is wrong there?

Since I have not seen Apple answer to this question and following conversations i will give a try to answer, based on my own initial troubles with FaceTime Group call and experience gained over a time on succesfull calls.

Firstly to be able to make and receive Group Call all involved parties has to be on iOS12.1.1 or later, which also answers all the Questions of iPhone 7 or 6 vs SE or any other. If the iPhone has 12.1.1 or later it can make and receive the Group calls.

Secondly, to make a call to several people at once, you have to have them in a group already. Like if you have a Family iMessage group or close Friends iMessage group. Without that you can make a group call adding new person to existing FaceTime call, but here is a caveat, that new person might not have his or her phone ringing indicating of a new call at the moment you added it to the call. You have to force ring him or her form the list of call participiants.

Hope this is useful.

The link you provided does not answer the question as to why the camera will not work on group facetime.
