Your Phone
Identify Phone Issues with a URL in the Phone Web Page
When the phone doesn't work or doesn't register, a network error or any misconfiguration might be the cause.
To identify the cause, add a specific IP address or a domain name to the phone admin page. Then, try to access
so that the phone can ping the destination and display the cause.
Procedure
In a supported web browser, enter a URL that consists of your phone IP address and the destination IP that
you want to ping.
Enter a URL in the format:
http:/<Phone IP>/admin/ping?<ping destination>
where:
Phone IP = actual IP address of your phone.
/admin = path to access admin page of your phone.
ping destination = any IP address or domain name that you want to ping. Only alphanumeric characters, '-',
and "_" are allowed as the ping destination. Otherwise the phone shows an error on the web page. If the <ping
destination> includes spaces, only the first part of the address is used as the pinging destination. For example,
"http://<Phone IP>/admin/ping?192.168.1.1 cisco.com" will actually ping 192.168.1.1.
Lost Phone Connectivity
Sometimes your phone can lose its connection to the call control system. When this connection is lost, your
phone displays a message.
If you are on an active call when the connection is lost, the call continues. However, you do not have access
to all normal phone functions because some functions require information from the call control system. Your
softkeys might not work as you expect.
When the phone reconnects to the call control system, you'll be able to use your phone normally again.
