Use this blog to make a call to mobile but its limited to seconds.So my suggestion is when your mobile balance goes empty this option is a good one
.Just signup in this blog ,that too not with much information just with mail id ,where you will immediately receive an authorization mail ...This option working perfectly in India . I made a local call and its 100% working in India .Guys use this link and try to call to different location and say the result by comments.Here is the site link .click here http://crowdcall.me/.
