That doesn't mean anything. Call agents can be anywhere, but show a common number for the company. I did some work, a couple of years ago, setting up remote phones for employees of a company in Mississauga. The employees, IIRC were in Ottawa, New Brunswick and Nova Scotia. They all had Mississauga numbers. For another company, employees in Edmondton and Vancouver, appeared in Calgary. I have done a fair bit of such work extending PBXs to remote locations.
As another example, at one company that I worked at a while ago, I had a line on my desk with a Seattle number, even though I worked in the Toronto area. When I used that line, it would appear that I was in Seattle, even though both the customer and I were in Canada.
With modern phone technology, there's often no relationship between phone number and location. VoIP makes it even easier and cheaper to do that.
I haven't lost my mind. It's around here...somewhere...
