Create a module that should be used in busy and no-answer extensions.

The module in case of busy can check* when the extension is free and then if the caller is free to establish the communication attempt (parameters to manage control timeout, different ringtones, called/calling prefix, notification announcement).

The module in case of no answer will periodically try to call the recipient if the caller is free (parameters to manage call timeout, a maximum number of attempts, different ringtones, calling/called prefix, notification announcement).

General parameters: maximum number of manageable requests.

(*) Control of extension being free is possible with a cron job or a check in every hangup for example
