What is exactly 'very bad quality of voice'?
Is it stutter? clipped? high latency? all of those combination?

Which version did you use? Have you tried the latest SVN?
Since recently there is a bit enhancement of jitter buffer for latency.

Type '--help' or see the menu for application samples (e.g: pjsua, streamutil).
For development, you can read the doc and samples :)

Not sure whether the quality problem is in jitter buffer though,
just in case you haven't seen this
