I didn't answer this call based on the number looking like so many (many, many) crap calls we get. But it turns out that this is AirGas, and they really are a supplier of stuff for trades that use welding materials, for example.
It's probably still a telemarketing call, so I'm not sorry I ignored it. And they probably have no reason to call a residence phone number. But as far as I know, they really are a business that sells refrigerants, oxygen, acetylene, etc...
