I can make calls over the internet with a 20ms delay, decreasing the
jitter buffer size will only help you breaking the quality.

The delay will depend on several things :
- your internet connection (obviously it should be ok here)
- if you are sending video or not
- the codec, using something else than G.711 could help
- the quality of your soundcard drivers in full-duplex (may I suggest
ALSA?)


However, a 150ms delay is acceptable. I'm surprised you can feel a 150ms
delay.
