So, this isn't likely to be the most robust suggestion and I'm not suggesting that it's ideal but it might address your problem quickly and cheaply while you work on a better solution:
As Andrew suggested, and based on your observation that the broken leg of the conversation is particularly outbound, you could try artificially limiting your outbound traffic on the WRT.
From the WRT admin menu (at least on my version):
Applications and Gaming --> QOS: Enable 'Upstream Bandwidth" Try setting it to something conservative like 800Kbps as Andrew suggested. If you're not using Asterisk inside and you're just using the Polycoms out to Unlimitel, are you using the WRT's MAC based or port based priority? You may not be applying QOS to the RTP traffic. It doesn't allow for a range of ports like the 10000-20000 that Asterisk uses, and I can't remember what the Polycom's use by default. What I'm saying is that if you're applying QOS to port 5060 then you're not actually fixing the voice traffic, just the control traffic. As for your 2600, I wouldn't count on getting much help from Allstream. Chances are they consider the Ethernet interface to be your demarc and the rest of the box is their network and they won't let you touch it. That's just my guess.

I am getting a number of complaints from the folks in my company wrt voice quality. We have a standard (?) Allstream T1 with 12 users and a simple Linksys WRT54GS router. It has some basic QOS settings which I have configured. I am using Polycom phones and my voip service provider is unlimitel so all the equipment and services should be ok. The quality issues are not consistent and occur periodically. They are best described as popping and clicking and broken (especially outbound) speech. My suspicion is that it's a QOS issue and so I am looking for a good QOS router that people have had experience with. Any other ideas relating to improving the quality would also help. Tony Davis
