    I see a some VoIP files here:
    http://www.usamtb.com/thibor/files/

    Can these help my VoIP setup w/ 15c?

    If so how do I install them or are they part of the 15c-Grcore6 upgrade that I already did?

    Already have mac of Sunrocket Gizmo set to Highest and Ports 5060 set to highest also. I have it on Auto in QoS an sometimes get garbled voice coming in?

    Thanks...
    ps,,,love this Thibor 15c on my SL for the last few months! Never a reboot needed!

    Unless you have a really slow link or run something that is constantly pushing your isp link close to max, then qos in my humble opinion is not needed. And in fact in some instances can cause more issues then it resolves. I personally run thibor 15c and vonage with no qos and double nat to the voip box and have no issues what so ever.

    90% of the time it's fine

    90-95% of the time it is fine....so I don't know.
    I can be downloading like mad when my wife is on the phone and it's perfect....next time I load one page and it breaks up the voice in her ear...?

    Suggestions welcome..:):) :biggrin: :biggrin:

    What you should be is get a network baseline. This is good practice in general but helps out so much so when troubleshooting issues like you are experiencing. It the problem is leaving your network then qos might help, if the problem is outside of your network and the next upstream device is not listening for qos marked packets then it wont matter either (assuming the packets get marked that way). With linksys i believe qos is just for queing and is only really going to help on outgoing packets. So to baseline your network just pick a couple sites from around the country that you can ping. For me i use google on the west coast, and vonage on the east (vonage works for me as they are my voip provider). I know google generally will run low 80ms delay and vonage will run upper 80 or low 90. Thats just from doing enough on a regular basis to know. Now anytime delay deviation gets to high i see sometimes 100ish all the way to 500 or 600ms. When this takes place i run a traceroute to see where the problem is, sometimes its in my own network, device just got hung up, sometimes its in a network out of my control. When it out of our control theres nothing we can do but keep an eye on it. Hope this helps let me know if you need anything else........

    Auto , % and Manual?

    I updated with the lastest SL 15c grcore6 a week or so ago....but I don't understand the updated QoS section.

    When I entered 400 Kbps as my 95% upload speed (speed was 420-430)....Save Settings then move to another screen in the Gui, then back to QoS screen I get randomly larger numbers where I had put 400, like 1755 in this latest case or I saw 12250 earlier? and once it switches to that number it sticks....What gives? Bug?

    Also what does Auto mean vs Manual?
    Does Auto use the % setting? and Kbps?
    Does Manual use both % and Kbps?

    What exactly does the % section mean.. % of bandwidth that is given to the highest QoS setup devices such as my MAC of my VoIP that I've already entered?

    I've had in set on Auto and 30% this last week with pretty good results with Sunrocket on a 4mb/420K connection.

    Just trying to learn the details so I can help others...mainly my BIL who has crappy Vonage performance and still using stock FW from 2-3 years ago.

    (ifican..thanks for the tips also!):biggrin: :biggrin: :thumbup:

    ***Bump...help anyone who has info on how QoS settings work..?

    What does Auto really mean vs Manual in QoS?

    What does Auto really mean vs Manual in QoS?
    I realize manual is like throttleing....but Auto seems to work funny see below.

    When I entered 400 Kbps as my 95% upload speed (speedtest usually fall was 390-424) then save Settings it looks fine. Once leave that page of the GUI and then come back to QoS page GUI that "kbps" number changes to 2456, or 4400, or to as high as 12250??
    Now remember my cable link is only about 400K up..so where are these numbers coming from?

    The only problem I'm having is *sometimes* the Inbound callers voice is garbled but never have a problem with the caller hearing my voice clearly. When I call out it's almost never happens - and the call quality is good!

    I'm using Sunrocket VoIP service - Innomedia Gizzmo behind a Thibor 15c SL.
    My QoS setup:
    1) Mac address - highest
    2) port 5060-5061 hightest
    3) Eth Port 1 - Highest(Gizzmo port)
    4) Eth port 2 Low
    5) Eth port 3 Low
    etc

    (sorry this is kind of a repost..but never heard a response:hearts: :thumbup:

    I have been using Thibor 15c with VoIP and Viatalk for about the last 6 months. I have it set to manual, and have the setting at 100% of my upload bandwidth. Everything works great, except for when Blizzard Updater for World of WarCraft kicks in, and is uploading via P2P to everyone. The VoIP service is unusable, and my pings to anything on the internet go to 800+ mS. This doesn't happen often thankfully!

    I'm also wondering if there is a better way to set the QoS, and how QoS on the Linksys router deals with upload bandwidth.

    Thanks for any information.

    TerminatorHTK -try this!

    TerminatorHTK - Try this in QoS:
    Here's what's working for me now.
    Set it Manual and then put 80-85% in the % box.
    Put your lowest upload # from about 20 speedtests. (mine was 405)
    (4mb/~425Kb cable ISP)

    Then set these rules in the "Catagory" section
    My summry looks like this:

    Priority Name Information
    Highest Sunrocket MTA6328-2Re - MAC XXXXXXXXXX (via Voip Device)
    Highest Sunrocket - port1 5060 - 5061
    Highest Ethernet Port 1 ---(Lan Port used by Voip device)
    Low Ethernet Port 2 -
    Low Ethernet Port 4
    Highest 68 Port 68 - 68 (sunrocket - may not need this)
    Low SSH ---
    Low SSL ---
    High Http --- (had this set to LOW but web pages clearly slowed on all pc's)
    Medium DNS ---
    Medium SSL ---
    Medium Ethernet Port 3 --- (wifes pc - complained about page load speed so I set her to medium that fixed her up)

    I was able to upload about 50MB of pictures to Snapfish while I was calling in and out with no problems! My call quality is very consistent now-- it's been about 5 days with these settings and the wife hasn't bitched once <GGG> about a bad call.

    more tweaks...DNS to Medium = good voice quality!

    I have also just tweaked again:
    I played with setting DNS to High, but this caused "garbled" voices on incoming calls about 25% of the time. I found setting that back to Medium or lower solved it.

    I've also unchecked / turned OFF "Prioritize ICMP"
    I'm not sure if this is smart .....but the voice quality seems even more clear - basically land-line quality.

    Does anyone have any reason why I should have Prioritize ICMP checked other than for PING testing?

    Unchecking "Prioritize ACK" wasn't smart....voice quality was not good at all, which I guess makes sense since ACK has to do with small packets, like a voip stream.

    I thought ACK only came to play for TCP packets. Isn't VoIP just UDP packets which don't send out an ACK after a packet is received? Maybe I'm getting confused here...
