I have not, but we've run these phones with SIP ALG devices before
without issue. I'll have them check.

Have you tried placing the CPE in “bridged" mode? It’s been a while since I’ve
done anything with Comcast CPE, but I remember their CPE doing SIP ALG when acting
as a router.

I have an employee who has recently switched to Xfinity cable service. Ever

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.
