Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series/T5 Series/CP860/CP920 IP Phones
744
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 SIP-T48G/S IP
phones.
The following shows an example for deleting all entries from the call history list when the
phone is idle:
For SIP-
T54S/T52S/T48G/T48S/T46G/T46S/T42G/T42S/T41P/T41S/T40P/T40G/T29G/T27P/T27G/T23P/T

/servlet?key=F1;OK;F3;DOWN;DOWN;DOWN;OK;OK.
Configuring Trusted IP Address for Action URI
For security reasons, IP phones do not handle HTTP/HTTPS GET requests by default. You need
to specify the trusted IP address for action URI. When the IP phone receives a GET request from
the trusted IP address for the first time, the LCD screen prompts the message “Allow remote
control?”. Press the
OK
soft key on the phone to allow remote control. You can specify one or
more trusted IP addresses on the IP phone, or configure the IP phone to receive and handle the
URI from any IP address.
If you are using SIP NOTIFY message method, you do not need to specify the trusted IP address
for action URI. But you should enable the IP phone to receive the action URI requests. When
the IP phone receives a SIP NOTIFY message 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?”.
You can use action URI feature to capture the phone’s current screen. For more information,
refer to
