At my previous MSP $dayjob, I ran into a few clients with Xfinity and Spectrum who both would mess with our VoIP solution UNLESS we enabled TLS SIP registration, we already used TCP on a non 5060 port by default to help with UDP timeouts and such. Now the RTP traffic could stay clear UDP, this was just the SIP part. ---------------------------------- Brandon Jackson bjackson@napshome.net On Tue, Sep 10, 2024 at 5:01 PM Michael Thomas <mike@mtcc.com> wrote:

What happens when you decrease your registration frequency? Do the phones stay registered? Have you tried TLS for the SIP transport by chance?
I manage a few phones on comcast across the country and have no problems.
In this day and age TLS isn't the default if not only choice?
