Tracking resource of a ConfBridge

I am experimenting with creating a ConfBridge using the ARI, which dials out to all of the extensions that should participate in the conference. When users answer their phone, they are in the conference.

My plan is to create the channels (originate) for my participants in the ARI and pass as query parameters the extension/context/priority of the point in my dialplan that adds the user to the ConfBridge.

The question is: do I need to do any cleanup after the ConfBridge conference ends (all channels hung up)? Am I responsible for tracking the channels and deleting them, or will Asterisk handle that (if the ConfBridge/dialplan is now responsible for them).

(This question is a follow-up to this discussion )

If you are using ConfBridge in the dialplan, then there is no clean up. The ConfBridge dialplan application handles it.
