◆ async_play_sound_file()

int async_play_sound_file	(	struct confbridge_conference *	conference,

Play sound file into conference bridge asynchronously.

If the initiator parameter is non-NULL, then the playback will wait for that initiator channel to get back in the bridge before playing the sound file. This way, the initiator has no danger of hearing a "clipped" file.

Parameters

conference	The conference bridge to play sound file into
filename	Sound file to play
initiator	Channel that initiated playback.

0	success
-1	failure

◆ async_play_sound_ready()

void async_play_sound_ready ( struct ast_channel * chan )

Indicate the initiator of an async sound file is ready for it to play.

When playing an async sound file, the initiator is typically either out of the bridge or not in a position to hear the queued announcement. This function lets the announcement thread know that the initiator is now ready for the sound to play.

If an async announcement was queued and no initiator channel was provided, then this is a no-op

Parameters

chan	The channel that initiated the async announcement

		struct confbridge_user *	user,
		struct conf_menu_entry *	menu_entry,
		struct conf_menu *	menu
	)

Once a DTMF sequence matches a sequence in the user's DTMF menu, this function will get called to perform the menu action.

Parameters

bridge_channel	Bridged channel this is involving
user	the conference user to perform the action on.
menu_entry	the menu entry that invoked this callback to occur.
menu	an AO2 referenced pointer to the entire menu structure the menu_entry derived from.

Note: The menu_entry is a deep copy of the entry found in the menu structure. This allows for the menu_entry to be accessed without requiring the menu lock. If the menu must be accessed, the menu lock must be held. Reference counting of the menu structure is handled outside of the scope of this function.

Return values

0	success
-1	failure
