| Changing to G729 could help you but there are more factors in the quality.
Main factor of course is your Bandwidth. Especially the upload.
Than latency, Jitter, and Packet loss.
Have you ever done a speed test on your network?!
One recommended link for a test would be: myvoipspeed.visualware.com or myspeed.visualware.com
Please post your results so we can discuss further.
