Configure SIP White and Blacklists
The
SIP Filter Lists panel
allows filtering of SIP URIs and User Agents to provide greater security
for 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. Note: If an incoming SIP caller is not on the
URI Whitelist it will be scanned using the
URI Blacklist
. If there is no match it will be scanned
using the
User Agent Blacklist
. A connection will be established if there is no match on either
Blacklist.
Important Note:
To only allow a predefined list of codecs to connect, add them to the
URI
Whitelist
and add a wildcard (asterisk) * to the
URI Blacklist
: all incoming calls will be
blocked except for codecs in the Whitelist.
