most commonly occurring problems.
Why does my phone display
“Application missing”?
If you have experienced networking
issues while the phone was downloading
the application from the TFTP server, it
is possible that the phone can no longer
retrieve the required firmware file. In
the event that the phone is no longer able
to communicate with the TFTP server in
its attempt to re-download the firmware
and the phone cannot locate the
application locally, this message will be
displayed.
The phone will display the following:
“Recovery web-client at: <IP
Address>”. The IP Address displayed is
the IP address of the phone. If the phone
is unable to receive an IP from the
DHCP server or has lost its record of its
static IP, the phone will auto-assign
itself the default IP 192.168.0.50.
To recover the firmware for your phone
in this circumstance, please perform the
following:
1) Launch your web browser on
your computer. Please note that
your computer will need to be on
the same network as your IP
phone.
2) In the URL, type: “http://<IP
Address>” (where IP Address is
the IP Address displayed on the
phone). Your browser will
launch the Vertical 480i IP
Phone Firmware Recovery
page.
3) Enter the name of the firmware
file that is on the TFTP server
and ready for download. E.g.
“firmware.st”.
4) Enter the IP of the TFTP server.
5) Press the Download Firmware
button.
Please ensure that the TFTP server is
running and accessible on the network.
If the firmware file is correctly located
on the running TFTP server, the phone
will locate the file and reload the
application onto the phone.
