Troubleshooting
This section describes solutions
to some most common problems
that can occur.
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.
Note: 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 Aastra IP Phone
Firmware Recovery page.
3. Call Customer Support and
request a <phone model>.bin.gz
file.
4. Copy the file to your TFTP
server.
5. Enter the <phone model>.bin.gz
file that is ready for download.
