Parameter

Permitted Values

Default

0~255.

For example: 10.10.*.* stands for the IP addresses that range from 10.10.0.0 to

10.10.255.255.

If it is left blank, the IP phone cannot receive or handle any HTTP GET request.

If it is set to “any”, the IP phone will accept and handle HTTP GET requests from any

IP address.

Example:

features.action_uri_limit_ip = any

Web User Interface:

Features->Remote Control->Action URI allow IP List

Phone User Interface:

None

To configure the trusted IP address(es) for Action URI via web user interface:

1. Click on Features->Remote Control.

2. Enter the IP address or any in the Action URI allow IP List field.

Multiple IP addresses are separated by commas. If you enter “any” in this field,

the IP phone can receive and handle GET requests from any IP address. If you

leave the field blank, the IP phone cannot receive or handle any HTTP GET request.

3. Click Confirm to accept the change.

Server redundancy is often required in VoIP deployments to ensure continuity of phone

service, for events where the server needs to be taken offline for maintenance, the

server fails, or the connection between the IP phone and the server fails.
