Configuring an IP Whitelist
Notes:
The telephone supports the IPv4 Internet protocol, with a prefix length of 0
to 32 bits. The network prefix provides the net mask for the IP address and
specifies how many IP addresses are released in a network range. The
larger the network prefix, the fewer the number of IP addresses that are
released.
Example:
Important: Only release as many IP address ranges as necessary. The
larger the released address range, the greater the danger of attacks.
5. Click Save.
6. Click OK.
Note: To delete an IP address from the IP whitelist, go to IP whitelist, click
on the IP address you want to delete, and then click on Delete.
Further steps:
– Save your settings before you leave the screen.
