VOIP Phone setup For Sonic/ATT

[Jongage]

Ok I hard wired everything in my house, garage, all bedrooms, office even outside. My goal is to plus a voip phone into any of the cat6 ports and use it.

I have never played with VOIP or other internet based phone setups before. And help would be appreciated.

Setup:
Sonic (At&t) Gig fiber internet.
AT&T Router, willing to change or purchase better one
unmanaged POE 48 port switch
(2) Unfi AP's

I've been using Ooma for the better part of 10 years - ported my old number over & plugged my old phone in and that's about all there was to it... I think that the price has changed over the years & am now paying about $5 a month for the service. I am sure that much has change since I made the switch and probably cheaper options out there but I've had no complaints
