Unless you want to bring in con$ultant$ to configure your obvious choice (the Cisco box), the first thing you should do is toss out your home-user router (the WRT54), and replace it with what David suggests. http://www.smoothwall.org/ also has a QOS plugin. Worked well for me, but it's way too cumbersome to configure...
If you like Linksys you should look at the RV-series routers, which comes with QOS. I've tried them, and they're an excellent choice. The QOS-feature is port-based, and is just an on/off setting. Usually QOS is a problem when it comes to downstream voice, since there's not much you can do with traffic heading your way from the internet. You should also check if your connection is optimized (for MTU for example): http://www.speedguide.net/analyzer.php If the test fails, chances are your Linksys router is not up to the task. If bandwidth is your problem you should set the Polycoms to use g729, supported by Unlimitel. If you have a lot of transcoding the problem might be with your * box CPU. Unless ALL your traffic goes through the same QOS router, no QOS solution will work. Finally, check your TOS setting in Asterisk. It won't help much if you don't have QOS all the way, but it doesn't hurt to set it correctly. -- Bjorn -----Original Message----- From: David Cook [mailto:[EMAIL PROTECTED] Sent: Thursday, May 04, 2006 3:01 PM To: [email protected] Subject: Re: [on-asterisk] Quality and QOS Router I have had excellent experience with m0n0wall. You can run it on a PC platform or an embedded device. Keep in mind that there may be more to it than the platform. Sometimes implementing QoS is not as intuitive as it sounds. dbc.
