The user agent whitelist/blacklist is based on the User-Agent header in the SIP INVITE. To whitelist/blacklist by user agent, the appropriate header must be present in the SIP INVITE to communicate the information to ClearIP. ClearIP does not recognize user agent information presented in the SDP.
User-Agent Header
Here is an example SIP Invite with a User-Agent header.
INVITE sip:+18554742536@sip.clearip.com:5060 SIP/2.0
Via: SIP/2.0/TCP sip.clearip.com:5060
From: <sip:+14045266060@transnexus.com:5060>
To: <sip:+18554742536@sip.clearip.com:5060>
User-Agent: Not Good Agent
Call-ID: 123456
CSeq: 1 INVITE
Content-Length: 0
If the SIP Invite contains a User-Agent header, the user agent name is populated in the User Agent column in the SIP Messages page.
Blacklist Specific User Agent
ClearIP can be used to blacklist a specific user agent by creating a rule in the User Agents page with Action set to Blacklist.
| User Agent | Action | Comment | SBC | Service Provider | Group | User |
|---|---|---|---|---|---|---|
| Not Good Agent | Blacklist |
