23.16.3 Configure SIP White and Blacklists
The SIP Filter Lists panel allows filtering of SIP URIs and User Agents to provide greater security
for your codec connections. For example, add trusted network codecs to the URI Whitelist in this
panel and only codecs using these SIP URIs will be able to connect. This is like saying, "if you have
the key you can open the door" and is perhaps the easiest way to filter outside access to your
codec's "front door".
It is also possible to add SIP URIs to the URI Blacklist and add user agents to the User Agent
Blacklist to deny them access to the codec. These blacklists also filter unwanted traffic and
increase the likelihood of rejecting unwanted traffic.
