Introduction

The SIP Calls report tracks threats over a specified time period.

SIP calls can be blocked due to a multitude of typical problems, such as:

• SIP parse errors
• Failed Authentication
• Accounting challenges
• Security features such as TDoS and DoS
• Exceeding Invite rate thresholds
• Failed SIP calls with 4xx, 5xx and 6xx class SIP failure responses
• Calls from Blacklisted sources
• Calls denied due to missing policy

Ideally these reports come back with no entries, but in typical deployments a certain normal level can be expected.
