ast_indicate will tell the channel to go on hold or off hold.
ast_queue_hold/ast_queue_unhold will queue a frame as if the channel has said it is on hold or off hold.</pre>

Instead, the hold action has some application specific behaviour associated with it - such as disconnecting the channel that initiated the hold; only playing MoH to channels in the bridge if the channels are of a particular type, etc.
One way of accomplishing this is to use a framehook to intercept the hold/unhold frames, raise an event, and eat the frame. Tasty. The patch attached to this issue accomplished that as a new dialplan function, HOLD_INTERCEPT.
In addition:
* ARI now queues hold/unhold frames instead of indicating frames directly. This allows for the Stasis hold/unhold messages to be raised.
* Some general cleanup of raising hold/unhold Stasis messages was done, including removing some RAII_VAR usage.</pre>
