Variable Values List
Yealink phones also support a combination of the variable values in the URI, but the order of the variable value is
determined by the operation of the phone. The valid URI format is: http(s)://<phoneIPAddress>/servlet?key=variable
value[;variable value]. Variable values are separated by a semicolon from each other. This method is not applicable
to T57W/T48U/T48S/T48G phones.
The following shows an example for deleting all entries from the call history list when the phone is idle:
For CP920 phones:
http://10.3.20.10/servlet?key=F1;OK;F3;DOWN;DOWN;DOWN;OK;OK.
For other phones:
http://10.3.20.10/servlet?key=F1;F3;DOWN;DOWN;DOWN;OK;OK.
Note: The variable value is not applicable to all events. For example, the variable value “MUTE” is only applicable when the
IP phone is during a call.
When authentication is required, you can use the following URI format: http(s)://user-
name:password@<phoneIPAddress>/servlet?key=variable value. If you are using a browser, we recommend that
you use Firefox.
The following table lists predefined variable values:
