For me there does not *appear* to be CGNAT as I can ping the client IP
and if we kill power to the modem the pings stop.

Are you aware of whether or not Xfinity is doing CGNAT for either of
you? Googling, I get conflicting results, some saying they use CGNAT,
some saying they don't. If they do, I wonder if their CGNAT routers
have SIP ALG enabled or disabled. Unfortunately, these are the sorts of
questions I suspect first level support can't help you with.

So not even the same area then.
We've now spent 2 hours on the phone and have gotten nowhere with
support.
Hoping someone here at XFinity can chime in and provide some offline
assistance.

Same issue... they are breaking something with registration. What
region
are you in? We are in North Central PA so we're routing

Your message is timely for me. I literally have the exact same
issue. I
setup phones for my daughter’s home and she got Xfinity. Everything
worked for a few minutes then I could not keep phones registered
after.

I have an employee who has recently switched to Xfinity cable

Ever since they switched their internet service their work phones

not stay registered for more than about 3 minutes.
These same phones have been used on many ISPs without issues.
The same
config has been used behind multiple levels of NAT without issues.
She was fine, until she switched to XFinity.
Of course, XFinity support is absolutely worthless.
Anyone from XFinity Tier 3 or such that might be able to offer
assistance?
I suspect it's something stupid with either NAT overload in the
modem
or the modem not keeping the SIP channels open.
I've tried playing around with registration times without any
success.
And again, we've never had issues with these phones or this setup
with
any other ISP.
