<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">One thing that may simplify your life here is to check out global_datastores.h and global_datastores.c. We store datastore information in those files if the datastore may be accessed by multiple source files. An example of one is the datastore that keeps track of all the interfaces that have been dialed by a channel to ensure that the channel does not get caught in a forwarding loop.
Using those files, you would not have to spread out the datastore information between channel.h, file.h, and file.c</pre>

<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;">Today, when a prompt is being played to a call waiting in the queue and an agent becomes available, the agent will not get the call until the prompt is finished. Both customer and agent is kept waiting.
With this rather big piece of code, we attach a generator to play prompts. The generator can, like all generators, be stopped at any time so that the agent (queue member) can get the call immediately.
The generator is now placed in app_queue, but could propably be moved somewhere else. It also changes functionality in main/say.c in order to be able to place those prompts in the same prompt queue for background processing. The same generator could be used to sevice conference bridges and maybe be added as a dialplan function at some point for background playlists.
