What a lot of people dont consider with VoIP is the qualiuty of their ISP and how well connected their ISP is to everything else. My ISP for example (only game in town that isnt dialup) has 1 feed from sprint, I am guessing a T3 (I live in a rural area) and no QoS of any kind. So in general they suck for VoIP because of the latency they add to the link. Many people I have talked to think internet access is internet access and the contention rate is never thought of. This greatly affects any review of VoIP. Of course a private IP network (again a lot of people think VoIP as voice over the internet not thinking about private networks) is usually better because it can be tweaked for voice apps specifically. Even if you dont have a private network adjusting packet size and jitter buffers for that link specifically can increase performance. It ends up being more than just tossing a box on the net with asterisk or whatever on it. Now that I think about it I havent looked anywhere for network performance tuning for voice apps, does voip-info have a wiki page? If not perhaps it should with general properties based on link types and all and possibly specifics for certain operating systems and/or network equipment. Since updating wikis is against my religion I am unable to do this (strict religion, forbids me from contributing to any GPL project - forced to release my code BSD style if free, or updating wikis). But there are enough people that do not follow the same religion as me. That may help with performance all around, and increase the user experience. -- Trixter http://www.0xdecafbad.com Bret McDanel UK +44 870 340 4605 Germany +49 801 777 555 3402 US +1 360 207 0479 or +1 516 687 5200 FreeWorldDialup: 635378
