If you get bad echo on your end, this is prolly acoustic echo (speaker 
feeding back into the mike) from his side.  Try having him use a 
headset/mike combo or something and make another test.  You'll see it 
will work much better...  In general with softphones, you don't want to 
use the built-in microphone/speakers on any pc, unless you put the 
volume so low it won't feed the microphone again.
The echo you experience, is your voice going out his speaker, feeding 
into his microphone again and then coming back to you.  That's why it's 
only experienced at one side.
