Will buy a SVG2482AC, will KX-TGM450S phone work?

I have some high sound hearing loss and wanted to get a landline via VOID with Comcast. Need to buy another Arris modem/router and looking at a SVG2482AC with VOID capability. Would like to use a Panasonic cordless phone KX-TGM450S which has features for hearing loss and not sure this will work with this modem and with Xfinity VOID phone service. Read reviews but not sure how accurate the advice is on Amazon. Arris (from India from the sounds of it) gave me a non answer answer which was call Comcast. The phone ports are regular phone jacks on the back of the modem which he could answer. I just don't know if the modem can translate the analog talking via this Panasonic phone via Comcast VOID? I don't know why it is so hard to find what will work with what. I know it is to Comcast's advantage to get folks to just rent and they figure it out for you but not doing that again. Too bad there isn't an easier way to list all phone models that work. I can see where some without any tech knowledge will just not even bother with the VOID since this has taken emails and calls and searching the internet. Honestly I am sick of my smart phones tracking me and when I heard that apps like Facebook have been turning on the smart phone cameras and their researchers watching folks. Then Apple immediately pushed out IOS14 where a teeny tiny green light will light up if you camera is turned on or an orange one will light up if you microphone is turned on. No one is looking at their phone all the time to see if they are being spied on! So migrating away from smart phones just done with all these companies bully folks around and spying on them. We use Xfinity for iphones but will probably ditch one and keep the other one in a drawer and turn it on for the few times we go out now.
