contain a variable named as “key” and a variable value, which are separated by “=”.
This method is especially useful for users who always work in the small office/home office where a secure firewall
may prevent the HTTP or HTTPS GET request from the external network.
Note
: If you want to only accept the SIP NOTIFY message from your SIP server and outbound proxy server, you have to
enable the Accept SIP Trust Server Only feature. For more information, refer to
If you use SIP NOTIFY message method, you do not need to specify the trusted IP address for action URI. However,
you should enable the IP phone to receive the action URI requests. When the IP phone receives a SIP NOTIFY mes-
sage with the “Event: ACTION-URI” header from a SIP proxy server for the first time, the LCD screen also prompts
the message “Allow remote control?”. Select the OK soft key on the phone to allow remote control.
Example of a SIP Notify with the variable value (OK):

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. If you are using a browser, we recommend that
you use Firefox.
The following table lists predefined variable values:
