telephone calls

if i want to make a call from my computer but i want the sound that the other person listens all comes from another computer, i tryed to take the mic and place it near the speakers but there is way to much noise and the person on the other side can barely listen to it, is there some kind of software to help me with this? or will i have to bye better hardware for it to work on perfection?
thank you all

 

I use a headset to prevent this. I'm not a fan of desktop mics due to this issue. I could you try to to turn down your speakers when talking.

 

Yes, headsets prevent the dreaded 'over-boost' you get from desktop microphones.
