Note
For security reasons, IP phones do not receive and 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?”. 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.
Procedure
Specify the trusted IP address for action URI using the configuration files or locally.
