Morning Everyone...blah monday!

We are looking to get a USA number which we can receive calls and make calls. It is important that people in USA call a "usa number".
Doing some googling and see google talk used to do this but apparently not anymore as things have changed to Google Hangouts.

Have tried google Hangouts and cant seem to find anything about acquiring a number.

We also made a test call from hangouts and it shows as "unkown number" is there any other way to do this? Doesnt have to be google hangouts.
