Works fine then dies...

Had the MJack for a few months. Hardware issues forced me to go from XP to Vista. Clean install of Vista, MJack fix applied and I thought all was well. A call made within the US, MJack may run ok, or fail. This morning on a business conference call, it stayed up a little over 3 minutes. Redial, MJack shows session in progress, but no audio. Same thing over the headset. Unplug MJack, different USB, all the tech recommended 'tricks' to no avail. Reboot sometimes works, sometimes not. No virus on the Vista machine. Every other application works just fine. Any suggestions? (besides getting Voyage or SkyPe)? Is there like a log or something I could look at to see where the error is occuring?

I was having audio and connection problems until I solved the technical problem of my computer's USB bus drawing over 500 mA, actually 580 mA, with everything plugged into the bus.

Try using a externally AC powered USB hub to plug the magicJack® dongle into instead of using the computer's USB port if there are 'many' other USB devices connected to the computer or if the magicJack® dongle acts erratically with audio and connection problems. [e.g. Startech .COM ST4200USB 4-PORT USB 2.0 HUB (ST4200USB)»(Cost $19.14)]

After the user has connected the magicJack® dongle for the first time, registered the device, and has the 'softphone' on the screen, the user should probably run TCP Optimizer to “tune” the computer to work with it in an efficient manner; it can be downloaded from the following website:

The program can aid both the novice and the advanced user in tweaking related TCP/IP parameters in the Windows Registry, making it easy to tune your system to the type of Internet connection used. The tool uses advanced algorithms, and the bandwidth delay product to find the best TCP Window for your specific connection speed. It provides for easy tuning of all related TCP/IP parameters, such as MTU, RWIN, and even advanced ones like QoS and ToS/Diffserv prioritization. The program works with all current versions of Windows, and includes additional tools, such as testing average latency over multiple hosts, and finding the largest possible packet size (MTU).

The user can use the TCP Optimizer by following these short instructions:

1. Choose the maximum Connection Speed from the slider bar (the maximum available bandwidth, in kilobits per second)
2. Choose the Network Interface, or check to Modify All Network Adapters
3. Pick "Optimal settings" from the radio-buttons near the bottom of the program
4. Click on the "Apply changes" button and reboot

It's so frustrating and where do I really address my problems to? Magicjack should be really known as magicjackshit. It was working fine, then it just refused to work anymore. I know it's not my machine.

We’ve had our Magicjack for about 6 months now and had the same issue, did a live chat with their customer service and it’s a simple fix.

Unplug your magicjack for a minimum of 20 seconds, plug it back in and start it again, it will work fine.

We automatically do this process every couple of days to ensure we don’t have the issue happening over again.
