Channel Events

Typically, events would be fired for new calls, when a call is answered, and when a call is finished:

  • channel_answer
  • channel_bridge
  • channel_create
  • channel_destroy

These events are sharing common fields below though their existence and their values, especially custom_channel_vars and custom_application_vars, varies and are depend on specific call types.
