Yes. We run lots of SIP UDP over many networks without issue. I feel like bloat is exactly an application for using UDP? With TCP won't that cause more bloat/delay? That being said, we generally see about 3-6 ms between end points and our PBX systems, so I'm not really worried about delay or bloat... just the XFinity firewall trashing active sessions.

What kinds of third party SIP are you all having so much issue with? I manage a lot of accounts using the big, hosted providers and plenty of the endpoints sit behind Xfinity/Comcast boxes without issue.
The dropping registrations just sound like timer and firewall configurations. By rule, I try to always go bridged mode with Comcast provided boxes, but even when not I can't recall having an issue like this except via the normal things like ALG being enabled or some type of security inspections causing trouble. And TLS is the way 100%
Is it possible it's being run over UDP? Is UDP even practical with SIP these days given bloat?
