Introduction

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

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

• SIP parse errors
• Exceeding concurrent sessions thresholds
• SIP Invites dropped due to missing policy
• Registrations dropped due to missing policy

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