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. 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.
Filter URIs and User Agents
1. Open the HTML5 Toolbox Web-GUI and click
Transport
in the
Menu Bar
, then click
SIP Filter
Lists
to launch the
SIP Filter Lists panel
.
2. Click the
Plus symbol
for
URI Whitelist
,
URI Blacklist
or
User Agent Blacklist
to add a
new item to the list.
3. Enter the new item in the text box, click to select the check-box and then click
Save
to store
the new setting.
4. Click the
Undo symbol
to undo editing and click and drag the
List symbol
to shift the
position of whitelist and blacklist items.
Important Note:
Some codec manufacturers allow whitelisting of calls by 'User Agent.'
Therefore, it may be necessary to enter a Tieline codec user agent into a non-Tieline
codec to allow it to connect to a Tieline SIP-enabled codec. From firmware v2.16.xx the
user agent in the codec is configured as "Tieline <Product Name> <Firmware Version>".
