phone proxy

I'm looking for a job, and some of the things i see online i think look like a scam. so is there so way to call suspicious phone numbers through a proxy so if it turns out to be a scam, they don’t have my real phone number?
P.S. I used the IP telephony topic because i use the magic jack, which i'm pretty sure is basically an ip phone.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

How about skype or gchat

Perhaps call from GMail?
you could use 141 in the front and it hides your number i.e. 141 0207 123 4567

i tried the 141 thing, but it kept saying the call couldn't be completed as dialed. is there some special way to dial with 141 in front of the number?
The number you are trying to reach is probably blocking private calls
