10.27 Action URI
The ALE Myriad Series phones can perform the specified action by receiving and handling an HTTP or
HTTPS GET request or accept a SIP NOTIFY message with the “Event: ACTION-URI” header from a SIP
proxy server.
10.27.1 Supported HTTP/HTTPS GET Request
Opposite to action URL, action URI allows IP phones to interact with web server application by receiving and
handling an HTTP or HTTPS GET request. When receiving a GET request, the IP phone will perform the
specified action and respond with a 200 OK message.
A GET request may contain a variable named as “key” and a variable value, which are separated by “=”. The
valid URI format is: http(s)://<phoneIPAddress>/servlet?key=variable value. For example:
http://10.3.20.10/servlet?key=OK.
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 phone screen prompts the message “Allow remote control?”. Press the “OK”
soft key on the phone to allow remote control.
