Action URL
Action URL allows IP phones to interact with web server applications by sending an HTTP or HTTPS GET request.
You can specify a URL that triggers a GET request when a specified event occurs. Action URL can only be triggered by
the pre-defined events (for example, Open DND). The valid URL format is:
http(s)://IP address of the server/help.xml?
.
An HTTP or HTTPS GET request may contain a variable name and a variable value, separated by “=”. Each variable value
starts with $ in the query part of the URL. The valid URL format is:
http(s)://IP address of server/help.xml?variable name-
e=$variable value
. The variable name can be customized by users, while the variable value is pre-defined. For example,
a URL “http://192.168.1.10/help.xml?mac=$mac” is specified for the event Mute, $mac will be dynamically replaced
with the MAC address of the IP phone when the IP phone mutes a call.
