Who has this number?

Someone from this number keeps calling for one of our IT guys by name. I can hear a lot of talking in the background so I assume he is from a call center and is trying to sell us something. When I transfer, he does not leave a message.

scammers...looking to get a name of a person who orders office supplies- i tell them different people do it, and give no names - they try to get a model number too,  which i do not give....when i ask if they want to send a catalog they just hang up - and try to call the number back - not is use - beware - give out no info
