Hi Mike,I think you said that any ICMP packets would be noticed, do you monitor the gateway connections as well?
I've seen some devices that send out relatively small TTL values and it can result in one way audio that is customer path specific. As mentioned before SIP/TLS is not a true VPN and the audio UDP will be hop counted across the Frontier network. They should send back an ICMP message when they droop the packet.
Just one more thing to check. Good luck. ~Glen On 3/10/2024 9:28, Mike Hammett via VoiceOps wrote:

I underappreciated the nuance of this issue. I thought we were talking about something closer to the physicality of networks, not packet inspection/filtering/etc.-- Alex > On 9 Mar 2024, at 08:11, James Cloos <[email protected]> wrote: > >>>>>> "AB" == Alex Balashov writes: >>>> I don't trust last mile networks to reliably deliver SIP calls.
