Thanks, Paul

I have tried to set tos=0x18 and this improved it a lot.

Also, looks like I have to seriosly look into setting up QoS on my firewall. At the monet I shut down P2P application running on one of the PC and this has helped too. Not sure why it was affecting delay. I would expect actual quality to degrade if not enough bandwith present.

Anyway, it is much better now.

Hi, all,

I got my * to work with voipbuster service. And it works quite well when I am calling USA or Europe. However, for local calls, I am experiencing long delays (About 1s). As far as I know, voipbuster application does not have this problem.

I am using IAX and gsm codec.

Any ideas on how to combat this?

Try all supported codecs with no jitterbuffer. If that won't reduce the delay it is probably due to their choice of provider for AU. Keep in mind that your internet route for IAX to them may be good but it is probably totally different from their route to AU PSTN.
