Relocating the ATA did not fix the problem.

I next tried removing the Uniden DECT phone system off the house wiring, and instead have only two corded phones tied in. In lots of testing and many long calls, at least for two days here, I am stable and noise/pulse free.

Has anyone ever heard of a DECT phone interfering with a VoIP box/service? This is the same DECT system I've had with ITPVoip for almost two years, without issues.

I am going to continue to run this way for a few more days to confirm.

Thanks,

Mike
