Update software on the WLAN IP Telephony Manager 2245
To update the software on the WLAN IP Telephony Manager 2245, reset
it. When the WLAN IP Telephony Manager 2245 starts up, it compares its
software version to the software version on the TFTP Server. The WLAN IP
Telephony Manager 2245 downloads the software from the TFTP Server
if the versions are different.
CAUTION
Always ensure that only the latest version of software is on the
TFTP Server and that earlier software versions are deleted,
moved, or renamed.
At startup, the WLAN IP Telephony Manager 2245 always uses
TFTP, if configured in the 2245, to compare its software version
with the version on the TFTP Ser ver. If the versions are different,
the WLAN IP Telephony Manager 2245 downloads the software
version from the TFTP Server, even if it is an older version.
Lock the system
Always lock the WLAN IP Telephony Manager 2245 in the SVP-II
Configuration screen before updating the software. Locking the WLAN IP
Telephony Manager 2245 prevents new calls from starting.
Reset the WLAN IP Telephony Manager 2245 after the update is complete.
Note: All calls in progress are terminated when the WLAN IP Telephony
Manager 2245 is reset.
Update software on the WLAN Application Gateway 2246
For information about updating the software on the optional WLAN
Application Gateway 2246, see Appendix A "Updating software" (page 168).
Update software on a wireless handset
With the WLAN system, you can perform over-the-air transfer of software
updates from the designated TFTP Server to the wireless handsets.
The downloader function in the wireless handset checks its software version
every time the wireless handset is turned on. If there is any difference in
the software version, the wireless handset immediately begins to download
the update.
On a clear 802.11a/b/g channel, the download process takes one minute
or less to complete.
