IP Table Configuration Interface
Add the authorized IP addresses to this table, and the gateways will only process the VoIP signaling from
authorized IP addresses. If the IP table is empty, the gateways will not perform IP address-based message
filtering.
If the gateway is deployed in a public network, you are advised to set IP filtering to prevent call theft.
