Chapter 4 - MultiVOIP Software
Upgrade Procedures
Whenever you upgrade your version of the MultiVOIP 400/800 software, you must first install the new
software on your PC. Then, download the Firmware, the Factory Defaults, the Voice Coders, and/or
the H.323 stack to upgrade the MultiVOIP 400/800 itself.
Before starting the upgrade process, view the current configuration and write down important data
such as your IP address, and voice channel configurations; these settings must be put back in place
after the software has been upgraded. Multi-Tech also recommends that you use the Print button on
the Phone Directory Database dialog box to have a copy of the phone directory contents.
Three utility programs included in the MultiVOIP 400/800 software are to be used only after the unit
has been repaired or upgraded. They are Download Firmware, Download Voice Coders, and
Download H.323 Stack.
Download Firmware
If you have obtained a new firmware version from the Multi-Tech Web site, the Multi-Tech FTP site,
or another source, do the following:
Win3.1 users - In the Program Manager, double-click the Download Firmware icon in the
MultiVOIP 400/800 program group. The Open dialog box appears displaying the file list containing a
single file, mtvoip.bin.
Win2000/NT/98/95 users - Click Programs | MultiVOIP 800 | Download Firmware. The Open
dialog box appears displaying the file list containing a single file, mtvoip.bin.
After you select the mtvoip.bin file and click OK, the Downloading Code dialog box is displayed with
a progress bar so you can monitor the download process.
After the new firmware file is downloaded to the MultiVOIP 400/800, the unit reboots and is then
ready for use with upgraded firmware.
