24.3. CEL (Channel Event Logging)

Channel event logging (CEL) is a new system that was created to provide a more flexible means of logging the details of complex call scenarios. Instead of collapsing a call down to a single log entry, a series of events are logged for the call. This provides a more accurate picture of what has happened to the call, at the expense of a more complex log.

24.3.1. Channel Event Types

Each CEL record represents an event that occurred for a channel in the Asterisk system. Table 24-7 lists the events that are generated by Asterisk as calls are processed.
