Hi
Yes, I know that I am using IAX2 and not SIP for my connection to teliax. IAX2 is the preferred protocol for connection to teliax. I have the firewall configured to prioritorize port 4569 for IAX2.
1) 4569 is only the IAX setup port. Edit rtp.conf to limit the rtp ports to some subset and then prioritise those instead 2) Uplink bandwidth is always the constraint on these lines. This is highlighted in this case 3) Shorewall can't correctly prioritise bandwidth whenever using some kind of DSL service or whenever the packets are encapsulated such as the cable service. Read the linux QOS faq for more info and as a workaround slash the theoretical bandwidth in half in your shaping script. This should get you working and you can tweak later 4) Monitor the QOS buckets as you make/break calls to check that all the packets are classified correctly. Otherwise your voip packets might be accidently in the bulk box
Basically VOIP goes from perfect to horrible when the jitter rises and packet loss goes up. Probably this is happening in your case
Good luck Ed W _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
