# View Blocked SIP user-agents

To view the list of blocked SIP user-agents as programmed by the MiVoice Border Gateway Administrator.

1. On the MiVoice Border Gateway main page, click the Security tab and click SIP User-agent filtering.
2. In the page that opens, under Blocked SIP user-agents, you can view the list of blocked SIP user-agents as programmed by the MBG Administrator.
   Note:

   - Blocked requests from a SIP User-agent means that MBG ignores the request and does not process the message or respond.

   - The result to a Hacker is that MBG with blocking enabled for the SIP User-agent, no longer looks like a SIP responding gateway.
