To All,
I just found out about this forum and any help or advice would be greatly appreciated.
I installed my MagicJack on a Dell E510 running XP SP2 with all the latest fixes. I am
using a Sierra Wireless 595u USB aircard to connect to the internet by way of sprint network.
Before ordering the MagicJack I ran a bunch of Voip test which showed that I should be able
to make and recieve calls with decent quality not great. I got my RMA number today to send
the device back but I figured after I found this site I'd give it one more try. I am using a
Panasonic Phone 2.4 GHz connected to the jack, the call quality is horrible. I also have Skpe
installed using a DUALphone. My Skpe calls from Los Gatos Ca to my brother in N .Y.C are
no problem reasonable voice quality. Trying the same with MagicJack results in what my
brother says is no better than a string and two dixie cups. I'm computer literate and know
how to change settings twiddle bits etc. Thanks in advance for your assistance.

There are two general possibilities:
One, your Internet connection is causing the trouble, even though the VoIP test you ran indicated otherwise, because you tested with unrealistic conditions.
Two, something about your MJ installation is not working properly.
Make a MJ call to verify that the quality is currently poor. Hang up and test to Boston at http://www.testyourvoip.com/ . Leave "Preserve Speech Quality" selected. If the result is decent, we'll do further tests for possibility two. If the result is poor, test again with "Conserve Bandwidth" selected. If the result is now ok, you won't be able to use MJ (because MJ does not presently support compression codecs, except on MJ-to-MJ calls), but Skype will be ok, because they automatically compress when needed. If the result is still bad, try a Skype call to confirm. On each VoIP test, save the detailed results, which will be shown separately for each direction.
I'm curious why you are using an EVDO modem on a desktop machine. If it's because your home is not served by DSL or cable, there might be one or more fixed wireless ISPs that would offer better performance, possibly at a lower monthly cost. If it's because you use it primarily with a laptop, try MJ on the laptop. If it is still bad, you can easily take the laptop and MJ to a location with e.g. cable or DSL, so you can confirm that your Internet connection is the problem. Also, you can see if EVDO transmission or reception is better at another location in your home.

Stewart,
Thanks for the advice and I will go through the steps you suggest and let you
know the results. As to why EVDO I live in the Sanata Cruz mountains near Los Gatos
California. You surmised that there is no DSL or cable and you are correct. Before Verizon
bought out our old provider GTE I almost had them convinced to let me put in a DSL card
at there junction box less than a quarter of a mile from the house. Alas no luck and Verizon
doesn't give a damn. My wife uses a service called Surfnet fixed WI-FI with a little Dish on the
Roof. Performance is good if we don't share the connection but every VOIP test I've made
on Surfnet shows a MOS score between 3.0 and 3.4. We tried Vonage a year ago but the quality
was unacceptable. SKYPE works fine for me but I'm trying magicJack because I'd love to get
rid of verizon for good. I have been modifying TCP/IP settings to see if I can impprove performance.
My wife uses a three year old IMAC G5 power PC and I may try the Sierra wireless USB there along
with the magicjack. One more thing when I clicked on MAGIC FIX everything works up until connecting
to server and it just spins. I've downloaded and installed but call quality didn't improve.

Coincidently, I'm typing my response from a Dell E510. I don't have an aircard though. I'd also try a different phone, I happen to also have a Panasonic 2.4 Ghz cordless I can't use it at all with my MJ. Other phones work fine.
Grab another phone and try it. I know your other IP option works fine, but it's worth a try!

Have you tried MJ on the Surfnet connection?
If may be possible to improve the Surfnet performance. Even if there is some expense involved, if you can have one good Internet connection instead of two mediocre ones, it will probably cost less and give a better experience in the long run. (You wouldn't have the redundancy that you enjoy now; I assume that your landline and/or cell phones would provide adequate emergency coverage.) Does Surfnet show a poor MOS even during the wee morning hours, when traffic is presumably low? Do you have lots of discards? Lost packets? Both inbound and outbound? What kind of radio are you using? What band? Dish diameter? Can you view the statistics in the radio? Can you 'see' more than one Surfnet access point? If so, have you tried them all? How far away are they? Do any offer the opposite band? Does Surfnet have adequate bandwidth to their upstream provider(s)? I presume that their towers are fed by wireless backhauls; do they have sufficient bandwidth? Is the system clogged by users infested with worms or spam zombies? By file sharers?

Stewart,
In answer to your questions about Surfnet the price is right 50.00 a month a can only get resonable recption from one tower and because I was early adapter I am not gated, my download speeds usually run from 700KBPS to 1.2 M I have their latest dish and they operate at 2.4 ghz upload is also
good however there is much more latency jitter and packet loss than with the sierra wireless aircard. In fact I tested both computers using the aircard
with the Dell being the host and the mac using ICS and also without ICS using a proxy server the router is a DLINK 665 wireless N. Response time was okay but since my wife sometimes likes to do online auctions I decided that for the time being will keep both services. Sprint gave me a good deal unlimited everything on the internet 60.00 a month. Programs like BITTORENT are blocked by Surfnet because of performance reasons. I did the test you required and results showed a MOS of 3.4 to Boston G711 with packet discards 4.5% no packet loss loss periods avg 160 ms jitter avg 13.
From Boston Mos 3.8 packet discards 2.5% no packet Loss loss periods avg 60 ms jitter avg 10. roundtrip latency 346 ms. With G729 results are a not quite as good but very similiar. I found that SKPE is using CODEC 729. I will try a different Phone per Zhotster's comment. Thanks for the help
guys and I'll let you know what happens. I printed the detailed results from both runs so if you need additional information Stewart let me know and I'll get it for you. No I haven't tried MJ on surfnet.

Thanks for the tip about the Phone, I grabbed an old GE table top slim phone and it worked. I was able to call New York City and talk with my brother and later he called me. The call quality was okay need to make it with a little less background hum. A question I have is will a DECT 6.0 base phone with additional handsets for other rooms work with magicJack. Again thanks for the help. If I can get a reasonable set up working I'll keep my two jacks.

Wow, I'm surprised that using the corded phone made so much difference. I'm guessing that there was interference between the EVDO modem and the Panasonic phone, even though the frequencies are very different. Try a test with a long cord from Panasonic base to MJ, so you can put the base ten feet from the modem. Also, test with the handset at least ten feet from the modem. If that works ok, you may not need to buy the DECT phone.
Some users have reported low outbound volume when using DECT with MJ, even with the mic volume set to max. So, you may want to buy your DECT from a local store, so you can return it if it proves to be incompatible.
The hum on your corded phone may be caused by AC voltage 'leakage' from your PC's power supply. If you get no hum when testing MJ with a laptop running on batteries, that's probably it. If so, you may be able to fix it by using a really old corded phone (that doesn't have an amplified mic), or by grounding the PC case (don't try the latter unless you are sure that you know how to do it safely).
It might be possible to greatly improve the jitter on your Surfnet connection -- let me know if you want some troubleshooting suggestions.

I'm surprised also Stewart that this worked, but it's possible that the phone is getting interference from even a neighbor's 2.4 Ghz network. I've had so many problems with bluetooth, 802.11g/b and 2.4 Ghz phones interferring with each other I'm going to just start tossing those old phones!Stewart wrote:Wow, I'm surprised that using the corded phone made so much difference.

Thanks for the help. If I have time tomorrow I'll set up my second jack on my Apple G4 Powerbook and try it on both networks. I'm quite familiar with TCP/IP and the relevant settings which I have tinkered with on Surfnet over the years. I tend to agree with Zhotster that 2.4 ghz phone is getting interference from Surfnet (2.4mgz wifi), microwave etc. For the fun of it I'll put a long extension cord and try it in the next room. Stewart I'm never too old to learn so if you have some suggestions for tuning on Surfnet which can help Jitter and packet loss, I'll try them out. I'll also call magicJack on Monday and see if they will void my RMA number so I can test longer rather then have to return the jacks in two weeks time. The PC case is grounded when I tried the phone this morning instead of hum a slight gurgle (water like) but call was okay not great. I'm planning on picking up a Panasonic Dect 6.0 with base and three additional handsets for under a hundred dollars locally next week and I'll see how that performs. I'll keep you informed of the results of my testing.

Troubleshooting Surfnet problems:
Can you see the jitter/loss by running e.g. and observing widely varying response times and/or lost packets? The rest of this post assumes that you can.
When pinging your default gateway (with PC connected directly to radio), can you see the jitter? (If the time is very short, e.g. < 2ms, the radio is probably set up as a router -- ping the next hop, which should be Surfnet's main router.)
If no jitter to Surfnet's main router, they likely have inadequate bandwidth to their upstream provider (unless that connection is also wireless and flaky).
Assuming jitter to main router, see if you get jitter pinging your access point. To do this, you need to find its IP address, by snooping or by asking Surfnet, and your PC must have an IP in the same subnet; you may need to temporarily set such an IP, if the addresses handed out to users are in a different subnet.
If there is no jitter to the access point, Surfnet has a capacity issue or problem with one or more of their backhauls. Discuss this with them.
Assuming jitter to access point, do you see it even during the wee morning hours, when traffic is presumably light? If not, there is probably a capacity issue; the same tower might provide service on another channel, or on 5.8 GHz. Ask Surfnet about these options.
Assuming jitter to access point at all times, it could be caused by inadequate signal strength in one or both directions; check RSSI values. If you can't login to your radio and Surfnet won't give you the password (some radios have a 'read-only' password to allow users to view stats but not make changes), ask them to check these values for you.
If RSSI is good, you could have interference at one end or the other (check retransmission counts, CRC error counts, etc.) There could be broadcast storms from various causes; check with Wireshark. Another possibility is heavy traffic at all times stemming from users infected with spambots, worms, etc. Use the traffic stats in the AP to confirm.
Once you have a general idea of where the problem lies, we can discuss what options might be available to fix it.

Stewart,
Thanks for the info and during the week I'll try the suggestions. I can address the small dish on he roof since
they replaced the old one in January and the subcontractor - installer gave me the address same subnet and
password. The tower I see and connect to is only 2.4 GHZ. There recommended setup since day one has been
to put an ethernet cable today CAT 5 and hook directly to your computer. If you use a router wireless or wired
to connected other computers and run them simultaneously they will not respond to problems. The same goes
for Internet Connection Services or Airport if you plug directly into a MAC. I have had nothing but performance
problems when my wife and I shared the connection during their peak times which is about 9:00 A.M. to 4:00 P.M. .
Hence the reason I got Sierra wireless USB modem, in my limited testing using a proxy server on my Dell my
wife said that performance was acceptable. When I order and get my Cradlepoint Router which supports the direct
connection of the USB modem I will test with both computers and if it is acceptable for my wife, I'll discontinue
Surfnet. There support is equally as bad as magicJack's automated live chat. If it were not for the fact that I was
employed for 37 years in the computer industry before retiring in 2002, I would have dumped Surfnet long ago.
Luckily for me I found this forum and a very savy guy like yourself or I would have sent it right back. Don't take
this the wrong way but do you work for magicJack?

I have the exact same card Sierra Wireless 595u with Sprint.
I did have that same problem for a few days and after a lot of hours spent on the computer I found the problem.
I run windows Vista (doesn't make a difference) and I had my air card unplugged for several days.
When I plugged it on my computer, I realize that the connection speed was too slow. After having the air card plugged into my computer for one entire night (remember, it has a battery and needs to charge) the connection improved many times over!.
Go to this site: http://www.speakeasy.net/speedtest/ and check your connection speed.
With your air card it should be something like 1850 kps (download) and 500 kps (upload). If this is true, than your bandwidth is not the problem.
I remember that once I had the bandwidth problem solved, I still had some problems with the audio.
The problems were three:
1) I was using a splitter (one for my Fax modem and one for the telephone line
2) I had the telephone line (from my MJ) plugged to the wall since I wanted to have several phones in different rooms at home. BIG MISTAKE.
3) I was using a cheap wireless phone.
I then tried plugging the phone straight to MJ with no splitter and the quality improved a lot. But eventually I could hear some breaks or little noises.
To fix this I went to walmart and got me a good phone bundle that had three phones with 6.0 technology. With this, I can now confirm that MJ works great with a Sierra Wireless 595u Air Card with great audio quality. I have MJ since a week ago and use it as my only primary phone. All I have to do is leave the computer on (with the hard drive and monitor turned off) all the time. Had it like that for several days now. I'm impressed.

Spaceman,
Thanks for the input, as stated in one of my posts above and answered by Zhotster the intial poblem was my 2.4 GHZ Panasonic phone. When I changed to an old GE slim line table top phone, calling and recieving worked but call quality although acceptable left something to be desired.
I have tweaked my TCP/IP settings and bandwidth is not a problem. I am going to get a DECT 6.0, probably Panasonic system with three additional handsets for other rooms and try it out. If the sound quality improves then I'll keep magicJack. If not I'll stay with my SKPE and keep my landline for emergencies and local calls at the cheapest rate. The download and upload rates of the aircard depend on signal strength, how far you are away from the tower, etc. Based on my location dowload speeds vary between lows in the 700 kbps to highs around 1.2M uploads vary between 300 kbps
and 700kbps. SKPE works great because it handles compression codec where as magicJack can only handle compression if it is from a magicJack to majcJack phone.
