Detailed Description

Call Event Logging API.

Todo:

TODO: There some event types that have been defined here, but are not yet used anywhere in the code. It would be really awesome if someone went through and had Asterisk generate these events where it is appropriate to do so. The defined, but unused events are: CONF_ENTER, CONF_EXIT, CONF_START, CONF_END, 3WAY_START, 3WAY_END, TRANSFER, and HOOKFLASH.

ast_cel_fabricate_channel_from_event()

struct ast_channel * ast_cel_fabricate_channel_from_event

(

const struct ast_event *

event

)

Create a fake channel from data in a CEL event.

Note

This function creates a fake channel containing the serialized channel data in the given cel event. It should be released with ast_channel_unref() but could be released with ast_channel_release().

Parameters

event

the CEL event

Since

1.8

Returns

a channel with the data filled in, or NULL on error

Todo:

This function is very expensive, especially given that some CEL backends use it on every CEL event. This function really needs to go away at some point.
