Got this call. Wondering if someone has information about it?

"Jason" with a very hard to understand East Indian accent called asking for someone who does not work here.  In addition to his accent he was hard to understand because of all the call center noise.  When asked for his name, company and call back number he stated he does not have a phone that he can be reached at so I said "Have a great day" and hung up.

A man with a heavy accent called and asked to speak with our company's supply chain manager by name and by title.  When asked what he was calling about, he said VOIP.  I explained to him that our supply chain manager does not make decisions regarding VOIP.  He insisted he speak with the supply chain manager.  I asked again what the call was regarding, he said VOIP.  I told him a second time that our supply chain manager does not deal with VOIP.  He said "Thank you" and hung up.

I keep getting calls from this number and don't answer but they never leave a message.

In my opinion it is a head hunter agency!
Asked to speak to one of our senior developer - they have no direct customer contact!
