Upgrading Software
As noted earlier the Upgrade Software command transfers, from the controller PC to the MultiVOIP unit,
firmware (including the H.323 stack) and settings. The settings can be either Factory Default Settings or Current
Configuration Settings.
NOTE: To upgrade a MultiVOIP from software version x.04 or earlier, an ftp primer file must first be sent to
the VOIP. Contact Multi-Tech Technical Support if you need this the FTP_Primer.bin file.
CAUTION: You cannot go back to x.04 or earlier versions using FTP. You must use ‘upgrade software’ via the
serial port.
NOTE: These ftp upgrade instructions do not apply to software release x.05 and above.
FTP Server File Downloads
Multi-Tech has built an FTP server into the MultiVOIP unit. Therefore, you can use an FTP client program or even
a browser to transfer files from the controller PC to the VOIP unit.
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, that is,
they may refer to the file transfer as an “upload “)
You can download firmware, CAS telephony protocols, default configuration parameters, and phonebook data
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.
The phonebook downloading feature greatly reduces the data-entry required to establish inbound and
outbound phonebooks for the VOIP units within a system. Although each MultiVOIP unit will require some
unique phonebook entries, most will be common to the entire VOIP system. After the phonebooks for the first
few VOIP units have been compiled, phonebooks for additional VOIPs become much simpler: you copy the
common material by downloading and then do data entry for the few phonebook items that are unique to that
particular VOIP unit or VOIP site.
To transfer files using the FTP server function in the MultiVOIP:
1. Establish Network Connection and IP Addresses. Both the controller PC and the MultiVOIP unit(s) must be
connected to the same IP network. An IP address must be assigned for each.
2. Establish User Name and Password. Establish a user name and (optionally) a password for contacting the
VOIP over the IP network. (When connection is made through a local serial connection between the PC and
the VOIP unit, no user name is needed.)
