I´ve got an iphone 4 and during the phone calls i can hear but i can´t be heard. any idea how to repair this?

During calls with skype or viber the other person can hear me but during normal phone calls my voice doesn´t sound. What can i do?
thank you

The iPhone 4 actually has 2 microphones, one on top and one on bottom.  The apps you're trying to make calls with might be using a different mic than the one that normal calls go through.  Check that the microphone mesh covers, and top microphone hole are not clogged with lint or other debris. 
If the microphone mesh or top microphone appear clogged, please use a clean, small, dry, soft-bristled brush to clean them.  Use the brush to carefully and gently brush the speaker and microphone mesh.
