Generally, the firmware file will be a self-extracting compressed file (with .zip extension), which must be
expanded (decompressed, or “unzipped”) on the user’s PC in a user-specified directory.

Upgrading MultiVOIP Firmware via FTP Client and Voip’s Built-In
FTP Server Function
MultiTech has built an FTP server into the MultiVOIP unit. Therefore, file transfers from the controller PC
to the voip unit can be done using an FTP client program or even using a browser (e.g., Internet Explorer,
Netscape, or FireFox, used in conjunction with Windows Explorer).
The terminology of “downloads” and “uploads” gets a bit confusing in this context. File transfers from a
client to a server are typically considered “uploads.” File transfers from a large repository of data to
machines with less data capacity are considered “downloads.” In this case, these metaphors are
contradictory: the FTP server is actually housed in the MultiVOIP unit, and the controller PC, which is
actually the repository of the info to be transferred, uses an FTP client program. In this situation, we have
chosen to call the transfer of files from the PC to the voip “downloads.” (Be aware that some FTP client
programs may use the opposite terminology, i.e., they may refer to the file transfer as an “upload “)
You can download firmware, the file system, and MSP firmware for the MultiVOIP unit with this FTP
functionality. These downloads are done over a network, not by a local serial port connection.
Consequently, voips at distant locations can be updated from a central control point.
