For Cisco routers, look at the fair-queuing modes (but stay away from weighted fair queuing as that can have a deleterious effect on VoIP traffic). Under Linux, check out http://lartc.org/ which deals with configuring routing under Linux with traffic shaping. For asymmetric configurations such as Cable/DSL, if you are willing to lower your download by and upload speeds by a bit, you can get nominal quality even with large downloads that would normally saturate your link. Under Cisco, look to setup multiple queues at different priorities. These can then be assigned to the WAN links (serial, etc). For Linux, look at http://lartc.org/howto/lartc.cookbook.ultimate-tc.html. That's what I use at home with my Vonage connection (soon to be a trunk line to my * install :). Drops download speeds from 1.5Mbit to about 1.4Mbit and uploads go from 256Kbit to 210Kbit. You're on your own across the Internet as a whole, but in the past 3 years I have seen very little to no tier 1 or tier 2 provider congestion, including trans-atlantic connections. YMMV, IMHO, etc. Regards, --- Gavin _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
