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.
The following shows an example of answering an incoming call then mute the call immediately:
http://10.3.20.10/servlet?key=ASW;MUTE.
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 predefined variable values:
