Zulu Phone Not Ringing when Ring Group or Queue contains too many extensions

Zulu desktop extension with softphone only rings right away when you call that extension.

In advanced settings what is
Default Follow Me Ring Strategy There are options, ringallv2, ringallv2-prim, ringall
what setting should it be?
what about "Default Follow Me Ring Time "

WebRTC I read about this, kept trying to find it in settings. It does not exist. It seems that WebRTC is not installed, nor is it an option to install. I followed the instructions
https://wiki.freepbx.org/display/F2/WebRTC+Phone-UCP#WebRTCPhone-UCP-Overview
There is no Module Admin to select in advance

Also advance settings do not have WEBRTC anywhere. UCP does not have webrtc.

How do i install via putty, I looked online for commands, and cannot find them for freepbx

I have one working Let’s Encrypt certificate.
is another type of certificate needed to allow the words WEBRTC to show up?
FOP2 does work with WEBRTC, but i wouldn’t know until i have it installed.

Thank you so much for your help. I’m sure another user will find this info helpful.

I read this post, but that does not at all show how to install webrtc

In my PBxact 40 system, I cannot find WebRTC anywhere in updates, modules, settings. What am I missing?
