Problem with international call

[jesslyn2011]

Not sure that everybody has this problem.Bought a freephoneline voip unlock key. when i called local, i was fine. but when I tried to use calling card to call international, i can hear the other side talking nicely but they couldnt hear me at all, i tried to use different calling card but it still had one way audio. I used my cell phone to call, it worked fine. I tried to use the difference freephoneline number to test out, it's was fine as well. It only happened with one number. Can somebody help me out please ?
