Is it _your_ voip service or something like Vonage riding over your network? Certain ones, like Vonage ship the router (like a Linksys RT31P2) with an overhead buffer/allocation preconfigured for around that same 128K to optimize voice quality. There's also a "bandwidth saver" setting that could be messing with them (http://www.dslreports.com/forum/remark,10277184) which I believe swaps the codec in use to something more or less bandwidth/QoS intensive like G.711, G.726 or G.729.
Ya can't blame a voip provider for carving out a piece of the/your bandwidth to keep their QoS at peak levels. As with most services, the more b'width, the better the quality - so the sub may have it set for peak voice quality and low b'width savings therefore each time their mail client pops or a get request fires out for a web page while the line(s) are in use, that's that. I suspect this will be the twist for working around portblocking issues...simply tweak the QoS to preferred levels for the house brand vs. the alternatives and this way, it's only slightly degrading the allocation for the competitor rather than blocking it altogether. Of course, who knows what's next out of Martin's office for would-be competitors... Couple of suggested links, fwiw: I've never used this thing before (anyone?), but it looks interesting: http://www.nonliteral.com/articles/hawking-broadband-booster-improving-voip- quality/ Might also try: http://www.voip-calculator.com/calculator/ Perhaps this would be an opportune time to sell him a service of your own that doesn't suck and is "optimized" ;-) for your network? Watch out...uh...uh....uh...<rant> Apparently everything you need to learn about QoS, deploying VoIP, reselling options and the gear can all be found, touched and tested in newsgroups online for free. You can also save a lot of time by asking the know-it-alls that don't attend events anymore. They are by far the best to ask because there's nothing left for them to learn or teach other people about the same old rusty technology that never, ever changes in any environment. Besides, their WISP and VoIP businesses have become way too massive and profitable to take time away to show others how they did it or give back to the industry w/o being paid. Don't lose hope though, just be patient with your requests, you'll get an emailed response at some point and I'm sure you'll have everything you could possibly require to build end-to-end QoS into that VoIPwork in no time - and for FREE to boot! If that weren't the case, I might point you toward a one of those zillions of pointless, overpriced convention options in the oversaturated event segment. Ya know the kind where people who are really good at stuff teach other people how to do stuff better. Those places where people who want to help each other build a huge, profitable and powerful industry and get together to try and avoid operating in a small, powerless vacuum for hobbyists. The kind of place where a know-it-all sits in a room and has his mind blown by what the guy across the room is doing, makes that peering agreement or bumps into someone that would love to help fund their expansion into the next town. Of course, who'd want to invest a whole $300-$500 in growing their business, that's serious crazy talk for any company to consider spending. No REAL entrepreneur ever found a way to grow by investing in their business, their staff, their industry, their infrastructure, spending time with their peers or by uncovering new ways to expand beyond just pure unlicensed RF connections. Besides, with all those annoying sales engineers trying to buy you dinner, that would get old real fast...Don't try to sell me stuff that might help me grow or improve the service, I just want you to underwrite most of the costs for me to learn things, have some free food & drinks and go away. Can you just spend the time to bring every kind of gear for me to see and NOT try to convince me to purchase it? Sheesh, the nerve of some people. How could they possibly try to operate a remotely profitable supply, service or manufacturing business when no other industry has ever done that. The best thing for every WISP do is be as cheap as you possibly can on every aspect of your business. Particularly for any successful outside capital investment or exit strategy to work, the network has to be pure homebrew. Stay home and away from other people, don't pay to join and support associations for your industry unless it's entirely via email for free. Avoid investing in anything and everything you can't hack together yourself with duct tape, warez, homebrew bridges and radio shack amps. RF engineering and running an insanely profitable, carrier-grade WISP can both be mastered and continuously improved via email for free. The only real challenge is bootstrapping and doing all this yourself while growing the rest of the business with an extensive, profitable service portfolio - ya know, that stuff beyond the connection (like VoIP) that might make you (more) profitable and keep customers around/happy with your service. Even more important than making your own equipment or running a single-product/purpose business is committing to running your business without a single bean counter, marketing and sales staffer or an install crew to get in the way. Besides, those people would just create overhead for the business and increase the email cluequeue backlog thread for the know-it-alls. So let's review: 1) be cheap, cheap, cheap - no matter what it is, just be cheap and haggle incessantly. If it costs money, it must be bad or some terrible, greedy company is trying to operate a profitable business (or a successful, substantially effective association) by creating it and offering it up for anything other than free. 2) learn everything in newsgroups for free, meatspace is for losers. There's only one way to learn everything there is to know about operating an incredibly successful and profitable WISP: free newsgroups with none of that nasty advertising support 3) build or reverse-engineer everything yourself with the cheapest possible components. If you really have to buy any gear, buy one so you can spend time tearing it apart, understand how it works and reverse-engineer your own version of it 4) if it just works, that doesn't matter - at any cost. Remember, you can always build a cheaper version of it yourself 5) run everything yourself in-house, never outsource, don't even think about staffing up unless the wife and kids will do it for free and don't need to be trained or learn anything outside of what's available in the newsgroups 6) stay home if at all possible unless you have to climb something to fix or install equipment. Knocking on doors for new business is just like attending a Chamber of Commerce meeting, meeting with a congressman or going to a trade show. 7) by all means, never, ever go to a silly trade show or conference and try to help someone else or even worse, lower yourself to learning from them in person. Paying someone for that would be the absolute worst thing in the world and could easily ruin your business overnight. </rantbufferoverflow> Ooops, sorry Brian - I hope the first part of this message was somewhat helpful and perhaps that latter was humorous at worst. Must be Monday or the over-caffeinated (disclosure:greedy trade show operator) here read a different thread while responding to ya. Go ahead Scriv, you can boot me now - I probably deserve it. cheers jp -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Rohrbacher Sent: Monday, August 15, 2005 9:54 AM To: WISPA General List Subject: [WISPA] VOIP I have a sub that says his VOIP goes to crap when I limit upload to 128k.
