I am getting these calls too. Since I have creditors calling, I don't answer non-local calls when I don't know the caller. So I can't answer this question. May be a creditor/collector.
It's Qwest in Utah. I spoke with someone at Qwest in Utah yesterday in support. They must be trying to reach me back. I'll answer it next time. I did a reverse lookup at Whitepages.com to find this. I should have done this sooner. Probably not a creditor call, although I owe them money too :o)
Oops wrong.... NOT Qwest. I got a call back after leaving a message at that number with what I thought was Qwest... it was Charles Ryder's company. I sent for info on this in the past, so it was not a totally unsolicited call. I could hear lots of calling going on in background though (a call center). Charles Ryder is a home business internet opportunity company. Probably some form of network marketing, but I don't know this for sure. They decided I was not a good match due (I think) to my lack of success in previous NM endeavors and the financial situation I am now in (that I told them about). Call them back if you are interested in a home internet marketing business.
