unwanted calls from this number

Frequently get a hang up call from this number.  Recently put our entire corporate phone system behind a firewall as we were being crippled by hackers since we have voice over internet.

Calls coming in from this number repeatedly. Claims to be related to Student Loan information verification. They don't collect the debt, they pretend to be getting your information for a separate service (job service, for example).  Also has used a "you won a sweepstakes" scam to collect your information and confirm it. Then they pass on the info to a Student Loan Debt collector such as Conserve.  Deal with this with care.
