Kazoo Call#

This application provides functionality related to tracking a call's metadata and executing call commands.

kapps_call#

Record containing information about a call. Generally populated from route_req and route_win AMQP payloads and updated by the winning application. It can be serialized and passed to other Kazoo applications for tranferring control of the call processing.

kapps_call_command#

Set of convenience functions for executing dialplan on a call. A thin wrapper around kapi_dialplan with argument defaults, as well as async and sync versions of some command (sync noted by the b_ prefix for blocking).

kapps_call_events#

Manages a cache of call events for Kazoo applications to ask for call events. At the moment, on startup, it registers with kz_hooks:bind to send CHANNEL_DESTROY events to the kapps_call_cache. The module exposes a function for Kazoo applications to query if the CHANNEL_DESTROY has appeared - this is typically used when setting up call processing when the call may terminate while setup is still being completed (and the destroy event is missed).
