Hi: I previously posted about the huge latency introduced by iax2. It is a problem introduced by the codec. in iax2.conf, i disllowed=all and allow=gsm and the RTT is the same as I do ping shell command. When i change from gsm to ulaw or alaw, then i have the huge RTT and high jitter and evntually the call get disconnected. when i use gsm, the call doesn't get disconnected. of course, i like to use ulaw, for the internet bandwidth i have, ulaw quality is better. i have asterisk 1.0.6 and i wonder if the older version had the same codec problem. __________________________________ Do you Yahoo!?

Either you or the far side simply does not have the bandwidth to sustain the communications. ulaw is about 80kbps, and gsm about 28-30kbps. It really sounds like you need to review your network. -A.

I think i had a download problem when i used ulaw, while i had enough for upstream all the time, it wasn't the case in the download.> > It really sounds like you need to review your > network.My current isp is one man company and has a lan internet sharing setup. i already placed an order last week with a better isp company and with higher bandwidth and routing.> _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com >http://lists.digium.com/mailman/listinfo/asterisk-users> To UNSUBSCRIBE or update options visit: > >http://lists.digium.com/mailman/listinfo/asterisk-users>__________________________________ Yahoo!

I think i had achawki, your measurements seem to be in kiloBYTES per second, while andrew was giving your rates in kiloBITS per second. -- Regards, /\_/\ "All dogs go to heaven." dinesh@alphaque.com (0 0) http://www.alphaque.com/ +==========================----oOO--(_)--OOo----==========================+ | for a in past present future; do | | for b in clients employers associates relatives neighbours pets; do | | echo "The opinions here in no way reflect the opinions of my $a $b." | | done; done | +=========================================================================+
