<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This fulfills some of the preliminary goals needed for refactoring parking. First I've created a bridging technology that is very minimalistic in nature (it doesn't do any actual communication between channels on a given holding bridge) for storing parked calls. This technology will also likely be used for queues and maybe some other stuff later on. Second, I've created an application that holds a reference to a single holding bridge which can place channels into the holding bridge. It includes some options for playing music on hold, ringing, and for breaking the bridge (such as in a queue/park timeout) after a certain amount of time.
I haven't implemented any kind of silence generation since I'm not sure it would be necessary and I'm also just plain not sure how to do that at the moment.</pre>
