I am currently running FreeSwitch very successfully, thanks to the help from many on this list. I am new to Linux so it was a challenge.

FS runs on a small LAN with about 5 other computers. The connection to the internet is DSL with 3M down and 768kb down via Covad. The ITSP is Flowroute.

If one of the computers does a big download, it messes with FS in two ways. If a connection is made, the voices are broken up, intermittent and difficult to understand. If the download is long enough, the connection to Flowroute is no longer usable due to registration failure.

Somehow I need to isolate the FS box from the rest of the LAN, or give its traffic precedence. Covad’s suggestion was to place the FS box in the DMZ. If I have to, I’ll get another DSL line and isolate it that way.

Is there a write-up anywhere that might help me with this problem, or lacking that, can anyone offer advice?

Get a dedicated DSL line. They aren't that expensive... I have four of them at my house!

Get a dedicated DSL. That'll work better than any sort of traffic prioritization or shaping (I've tried).

Depending on your average channel use and codec, you could probably go with the smallest package and be fine.

4 sounds a bit overkill. Hope you got a good deal. But yes isolating
it from general internet traffic is ideal. There are other methods to
reach that goal but they get rather complex once you realize all the
things that can effect calls. =/

I agree, it might be a "dirty" solution, but its so much easier than
trying to get QoS running on a DSL line, or learning how to run a
traffic classifier...

Lars, If your ISP is a COVAD partner, ask them to reprovision the line for VOA (voice optimized access). They will provide you with two seperate VLANs (one for best effort data and the other for real-time/voice traffic). If they are unable to do so or do not understand your request, feel free to email my off list and I can help you. The cost difference should be minimal unless you move to "second line" (a/k/a "naked", "unbundled", or "dedicated") DSL. -metik ----- Original Message ----- From: Lars Zeb (larclap@yahoo.com) To: freeswitch-users@lists.freeswitch.org (freeswitch-users@lists.freeswitch.org) Sent: Monday, October 26, 2009 1:37 PM Subject: [Freeswitch-users] Setup advice on small LAN I am currently running FreeSwitch very successfully, thanks to the help from many on this list.

Unfortunately, most North American providers ignore (and in most cases reclassify) it before it reaches their border routers and it will be treated as best effort. Typically, the problems are introduced within the first mile and its simply a matter of getting the packet safely pass the edge unless your ISP is grossly oversubscribed (in terms of servicable traffic limited by their particular hardware and bandwidth). If it is too costly to move to "second line" or "dedicated" DSL, he should be able to improve audio quality by acquiring a broadband router that has minimal QoS capabilities and adequate CPU (since the majority of them use software based queuing and packet fragmentation). The only caveat is that the degree of success can vary between firmware versions. Some of the consumer (gaming) or small business (VPN) grade routers work well (Linksys, DLINK, etc.). -metik From: Tihomir Culjaga (tculjaga@gmail.com) To: freeswitch-users@lists.freeswitch.org (freeswitch-users@lists.freeswitch.org) Sent: Monday, October 26, 2009 5:34 PM Subject: Re: [Freeswitch-users] Setup advice on small LAN If one of the computers does a big download, it messes with FS in two ways.
