2. Then go to this ftp site and download the firmware fix. The zipfile is: mvpngav-6.11.28-10-04-11.zip


3. Use the old software to read the MultiVOIP settings and write it down. You can also do a screen 

   shots of each pages and save it in paint program so that you do not have to write it down.


4. Uninstall the old software first and then install the latest software in. Make sure you note the 

   path where the new software is installed at. We need it later steps.


5. Unzip the firmware fix into a /Temp folder. Then copy them all into the directory where you have 

   latest MultiVOIP software installed in step 1. This is usually in C:\Program files\Multi-Tech Systems\.


6. Connect your serial cable to your MultiVOIP device.


7. Start button -> Programs -> MultiVOIP xx.xx -> Upgrade Software -> Make sure you select 'Factory Default'.

   This is a must.


8. Once done, go to the System Info page and check the firmware version. Pls, ignore the date and year that displays

   on the GUI title bare. Reconfigure your MultiVOIP and go to IP page and select 12A.MMidnight option 

   under Reboot Time drop down box. Click on OK and do a save and reboot.


9. Then select 'Date and Time Setup' option to set the clock on the MultiVOIP. The new firmware looks for the time on

   this internal clock to do the reboot.


10. You are done.
