I recieve quite a few of these calls from locations as Salem,Braintree, Milton ,Boston Ect !... Theres never a message left and neither I or my wife answer these calls. Then, After 2 or 3 days we recieve calls from New Jersey, Illinois, Delaware, Maryland Ect. So whomever they are, Their clever enough to know that Blocking "All" these numbers are not tangible !....

Caller identified herself as Tina of Summit Technical Services.  She claimed she had a copy of a previous resume and wanted to discuss a job opportunity.   She left a call back number that was different from the callerID number  781-848-4321 and that is the number for Summit's Braintree (MA) office.   It appears they are a temp agency.
