WHITELIST PROXY
To protect your IP phone network, you can configure a “
Whitelist Proxy
” feature that screens
incoming call requests received by the IP phones. When this feature is enabled, an IP phone
accepts call requests from a trusted proxy server
only
. The IP phone rejects any call requests
from an untrusted proxy server.
The whitelist is dynamically updated (i.e. the phones are able to refresh and resync the whitelist
[without a reboot] if the IP addresses corresponding to the proxy FQDNs are changed on the
DNS server).
The IP phone monitors the following events and an update is triggered if required:
• 200 OK responses to REGISTER requests if the peer’s IP address is not currently in the
whitelist.
• 200 OK responses to INVITE requests if the peer’s IP address is not currently in the whitelist.
• INVITE requests from untrusted proxy servers.
CONFIGURING WHITELIST PROXY USING THE CONFIGURATION FILES
You use the following parameter to configure the whitelist proxy feature using the configuration
files:
• sip whitelist
For the specific parameters you can set in the configuration files for setting Whitelist Proxy, see
Appendix A, the section, “Whitelist Proxy Setting” on
