INCOMING audio garbled - anything else I can try?

This forum includes tips for maintaining the best audio quality possible with the Ooma System. If your Ooma system is having issues with dropped calls, static audio or echo, look here for assistance.

Yes, I did a full wipe of NVRAM before loading DD-WRT. No, it's an old (v2) 54G, not a 54GS. No, I'm not using SP1, I'm using an older build (9517M). I haven't touched the router since before I got the Telo. Even if I have DD-WRT problems (which I doubt), I have given the telo a static IP (something everyone should do, IMHO), so the DD-WRT DHCP lease problems should not affect it.

I've found that DD-WRT can do effective QoS throttling if set up properly (in my case, when I used it, I had the telo's MAC set as the only premium service, no port-based throttling). What makes it nearly impossible to configure is that you can't account for "turbo boost" easily, and you can't separately throttle WAN & LAN, so you have to throttle LAN traffic too much.

I don't think QoS (or bandwidth issues) is a problem, since I can monitor LAN and WAN traffic when I have the problem. Nothing is sucking up bandwidth when the telo goes into "garbled mode." That's why I think this is either a problem with my telo (either a defective unit, or just a bad piece of equipment) or with something on the other end of the line. No one at Ooma's tech support has been able to come up with any diagnostics I can use, so I can't figure that out.

This setting works for some people, and for others it doesn’t work. It works for me.
So, you think that the telo throttles itself? That would be a huge bug in their QoS logic. Since the telo QoS is only supposed to throttle downstream packets, so that packets generated (or delivered) by the telo get through. You're saying to set the telo's QoS to higher throughput than the network can possibly achieve might stop that buggy throttling? I'd say it's a longshot, but I can try it and see if it makes a difference. That sounds like something that should have been fixed if it is happening.

If this is the case, wouldn't it just be best to set the telo's QoS numbers to something ridiculously high?
About two years ago one of the Ooma Telo firmware updates was supposed to fix this problem. But it seems like for some Ooma Telo builds, it there is still a problem or it didn't work. I've never tried a ridiculously high setting?
