I convinced my dad to sign up for Voipo a few weeks ago, but ever since he hooked up his RT31P2 there's been a constant whirring noise in the background. It's always there whether on a call or not and on both phone ports. He's tried different phones, disconnected it from the Internet and even moved it to another room to no avail. The annoying sound is definitely coming from the RT31P2. A couple of weeks ago he opened up support ticket JIO-547724 and they made a few adjustments to the ATA and closed out the ticket without even waiting for a customer response, but it's still there.

I was at his house last week and the sound is very irritating and not the norm. The only way it can be tolerated is by turning the phone volume all the way down. It sounds like he's got a bad ATA to me, but I'm not really familiar with the RT31P2. Has anyone else had this problem? If so, what was the fix?
