I see this is happening to others with the same device. It has pretty much happened since we bought it just over a year ago, but we assumed it was the wireless phones connected to the router. It is not. We bought a wired phone just to test. Our callers often hear random beeps when talking to us, and I hear it when calling home. Cell or landline calling, doesn't matter. Don't hear it on the "home-phone" router end, it is just heard by our callers. Insanely frustrating, and appears to be a common problem with this expensive unit.
There might be a defect with your 4G LTE router.
Best first step would be to contact VZW support for warranty replacement/swapping options. If you get the problem on a 2nd 4G LTE router then it might be a compatibility issue between your phones and the voice function of the 4G LTE router.
We definitely want to help eliminate the aggravation the beeping noise is causing, doncon94. All calls should sound clear with no interference. Let’s take a closer look into this. Does this happen on every call? How long has this been an issue? Have you reset the device?

Virtually every call. Since we bought it (although it took a while to
diagnose). Yes, have reset the device.
