Awesome guide, thanks for sharing!  And kudos to the PowerPBX developers 
for taking the time to write and maintain that blog post!  I'm also 
noticing they've been keeping up the good work, since they also have a

 From my limited knowledge on this topic, STUN/TURN is more important 
(critical) if you have WebRTC endpoints connecting.  If the endpoints 
are only SIP UAs and you have NAT issues, then IMO you are beter off

It all depends on how redundant and secure you want to make it.  Of 
course, each of these is an optional nice-to-have.

You will know once the clients start complaining about "one-way audio" 
or "no audio at all".

Congratulations for getting everything set up!
