Realistically, the endpoints are what really count, because that is where packets gain payload. The mtu at your endpoints have to be equal to or smaller than the smallest mtu of the path between endpoints. The optimal mtu is always going to be the mtu that fits the pipeline between endpoints without splitting the application layer's payload, therefore your mtu at your pc should equal the lowest mtu along the path between endpoints. Anything lower than that is not necessary unless you are unsure of the path mtu. In that case a little too low is better that a little too high., but going is low as 200 is just ridiculous and would only increase the aggregate latency of payload delivery, unless of course your path mtu is 200. Not likely unless your using dialup or pony express. If someone has a "stutter"problem they may want to see a therapist, but lowering endpoint mtu below path mtu isn't going to be of any help. Jitter on the other hand is not an mtu problem but rather is because of packets that arrive out of sequence and the transport protocol is udp. Since jack's jitter buffer is set in the registry and changes made will get overwritten the next time jack starts, then the next option is to set qos, tos, or cos if possible. Start by adding qos to your ip stack in Windows, and set any settings your router may provide. Sip should be "cs3" and rtp should be "ef". Simple qos settings would be priorities 3 and 5 respectively, or "maximize reliability" and "minimize delay" respectively. Tos values of 0x68 and 0xB8 are good if appropriate.for your router. Settings that maximize throughput or bandwith are tempting but won't provide the result you seek.

Anyone care to give specifics on how they configured QoS for MagicJack?

In reading this sticky's title, I know that's what I was hoping for and not an MTU debate! Rolling Eyes

Image,

I'll see your bet and raise you one. I don't even know where you go to configure the QoS.

I did turn the one in my router off because I made a completely hypothetical assumption that you don't want two QoSes running on the same system.

So:
1. Router QoS = off.
2. Windows Vista Ultimate QoS = on and un-tuned (don't know how, didn't know you could).

I have dsl-I ran the voip test last week and it was not good. I installed the Hawking HBB1 Broadband Booster-The new test shows a perfect score and the sound is great! It's worth the 25 dollars!

I got mine on sale at Fry's Electronics. I don't know what all it helps but that sounds like it would. I works to improve the connection speed and my dsl speed has definetly improved as well as the voip quality-Check it out here

My sister in the sticks of FL needs something like that for her Verizon Wireless card. I cant seem to get her a good conversation out of her MJ.. I'm in WI so I cant help from here.. Please let me know how you would set that up with her configuration of the wireless card. Gerry, do you have a wireless sprint connected somehow to a router? How did you do that?? I am curious to the scenario and configuration on that. What router did you use so far? Sis needs it!!

I am using a Kyocera KR1 router. It accepts a PCMCIA wireless card and gives you both wired (4 RJ45 jacks) and 802.11g wireless. It is very cool. It also runs on 12V and comes with both a cigarette lighter plug and a wall wart. I am involved in emergency communications, so when I put it in the vehicle it gives me a rolling hotspot for all intents and purposes. I have used both Vonage and the magicjack with it. I'm not sure why but the Vonage phone will generally outperform the MJ. I'm hoping that with the release of the new codec for the mj the performance will improve. I am also a T Mobile subscriber and with the new Curve from Blackberry and the $10 a month phone@home plan you can use your cell phone over wi-fi to make unlimited calls for the $10 a month. So, if you take the Kyocera router with you and you initiate the phone call on the Kyocera using wi-fi and transition to the cell system by walking away from your car or turning off the router the remainder of the call will not be charged against your minutes...so how cool is that!

For XP, Cablenut works well in setting all values for DSL, download it and the Upgrade settings. DSL normally has a 1492 DSL value, the RWIN also very important (Cablenut will set this according to your computer memory, speed and latency calculations). Doesn't work with Vista (what does!). There is a small application called WLAN Optimizer .NET that shuts down the WLAN Zero Config service. Speaking delays sometimes occur when VISTA auto searches for more optimum connections and can affect your connection whether you're using WLAN or wired. QOS, am using it but am not convinced of it's need, bandwith needs with MJ is just too small.

I have the same thing going on and mj is trying to help....and I am trying to read here and I am not very good with computers so thought the one two three would work but it getting to be more work. I wish it was easy cause right now my head is hurting and I have try three different phones thinking it was the phone and the (mj chat) person said it does not work with wireless have to be hooked up to the router. so I wrote to ask for a return number and (mj chat)another person has try to fix it and we went deeeper in to my computer and then down loaded divx which I have not figure what that has to do with this.

I too am in Canada (using a 7MB ADSL connection through sympatico) and I have a.5 second delay. I have optimized my stacks, my router settings, I have done the magicfix, I installed the DIVX codec (MJ support asked me to do this) and I still have it

Everything else is great. No noise, static, jitter, etc. Just a slight annoying delay. I use to use Skype Pro before and never had this issue.
