Variable Values List

Yealink IP 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
T48G/S IP phones.
The following shows an example for deleting all entries from the call history list when the phone is idle:
For CP920 IP phones:
http://10.3.20.10/servlet?key=F1;OK;F3;DOWN;DOWN;DOWN;OK;OK.
For other IP 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 or http(s)://<phoneIPAddress>/servlet?key=variable
value&@username:password.
The following table lists pre-defined variable values:
