Re: [Asterisk-Users] QoS What to do?
If your DSL link is the bottleneck, rather than earlier hops back through the providers network, the provider could also prioritize VOIP packets going up the DSL line. That requires a cooperating provider, of course. You may also setup a linux box (or another QoS supporting router) on the inside and tune the communication with queueing there. Read the LARTC howto for more info. roy ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

That's what I thought until we were involved with diagnosing a VoIP problem on the east coast. The site had a dedicated DS3 with no other data users. VoIP was choppy and not really usable, however a dsl connection at the same site sounded good using the exact same equipment. We found that someone had mucked with the network settings in XP turning off the QoS support. After re-enabling only that single option and retesting did the DS3 provide exceptionaly good quality. Turned out that Worldcom had in fact enabled QoS (on at least a portion of their backbone network) between the east coast and midwest. It impacted both directions. I was surprised, and I've been doing 100% corporate networking for 20+ years. Rich ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

Many routers allow you to prioritize certain types of traffic -- effectively letting the packets jump the queue. If you strictly prioritize the voice packets over data packets, you'll probably do quite well. 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
