Unable to call specific exchange

[jwdad]

My office uses a VOIP system. When I try to calling my office number using Ooma I get a fast busy signal. I am able to call the office number with any other phone, so I assume the problem has something to do with Ooma. Any suggestions? The office number is local, within the same area code, so I only dial the 7 digits. I have also tried calling all 10 digits with the same result.

I recommend you call support.

My father lives in a fairly-remote part of rural Wisconsin, served by CenturyLink (previously called CenturyTel). I had similar problems calling him, when I first got my ooma Hub. I called support and reported my ooma number and the troubled area code and exchange. It wasn't long that they must have contacted CenturyLink, because about two days later, the problems suddenly cleared up. It's been fine since then - that's two months now.

Good luck.

EDIT: Minor clarification about what I told support.
