Re: Cloudfront Blocking IP ranges

Hi Quentin, Have you had luck finding a Nuestar contact? Last time I searched I came up empty. Almost all the sites never respond when we put a ticket/email in saying we are blocked. We are likely going to start sending certified mail from legal and see if that gets any attention. It's causing a l

Re: Third Party VoIP Over Xfinity

Of course, Comcast sells its own VoIP services, which I'll bet work just fine; so they don't have a huge incentive to go out of their way to make their competitors' product work on their network. Jim Shankland On 9/11/24 2:19 PM, Tom Beecher wrote: How can such a large company have somet

Re: Third Party VoIP Over Xfinity

Does this apply only to customers using their proprietary gateway or customers on a CGNAT service with them? I have been a Comcast customer for years, with my own equipment, and have never had issues using Polycom SIP phones on RingCentral. This is getting a little concerning for me as we are p

Re: Third Party VoIP Over Xfinity
