That makes so much sense! Can't believe I didn't put that together. Thank you so much! That will help me with another issue I ran into recently.

Back to this issue. With my new information I thought it'd be easier just to ask a nearby employee if I could borrow their phone which I know works (and is an analog phone) -- I plug it in and still get no dial tone. I can call the building from my cell and dial the extension and the line will ring and I see my number on the caller ID but when I pick up the phone (hit Talk) it is silent and my cell phone continues to ring as if no one picked up.

I have also tried a different phone cable just to make sure that wasn't the issue.

Thanks!
