How to get free or almost free calls to USA from Phillipines

[Yogi Shah]

I've hired a telemarketer in Phillipines to make calls on my list in NJ. I provided a skype number but he said it doesn't always go through. So, I just got a free google voice local number but he said he's not able to login.  I don't know if he can't login because he's in the Phillipines or why he can't log in.  What suggestions do you have for me to have him use to call into USA from Philippines?  If google voice is good, how do you set it up to work?  Can it be done for free or low cost?
