The other day, I was uploading a file to my companies ESXI server (rather large at 60GB) and I was also talking on my Grandstream GXP2120 BYOD device and my voice was degraded to the other callers, although I could hear them very well.

I have Verizon Fios, and a 25down/5up package, and the upload was only taking a half a megabyte or so. I know I had plenty of bandwidth and my laptop and the Grandstream were the only 2 devices connected to the router.

Anyone have any ideas? I have worked with technical support and they have a ticket open, Verizon scanned my router and connections and said all checked out but decided to send me a new router anyway.

Anything else I can check?
