If you're using SRTP and passing keys in the SDP announcement, it would be rather pointless. I don't know how common it is to do the inline keying for SRTP which I understand is how VoLTE works, but seriously I can't imagine why anybody would not use SIPS: Nothing good came come of that.

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.

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?
