29  *
30  *             Each dynamic agent in each queue is now stored in the astdb.
31  *             When asterisk is restarted, each agent will be automatically
32  *             readded into their recorded queues. This feature can be
33  *             configured with the 'persistent_members=<1|0>' setting in the
34  *             '[general]' category in queues.conf. The default is on.

36  * \note 2004-06-04: Priorities in queues added by inAccess Networks (work funded by Hellas On Line (HOL) www.hol.gr).
37  *
38  * \note These features added by David C. Troy <dave@toad.net>:
39  *    - Per-queue holdtime calculation
40  *    - Estimated holdtime announcement
41  *    - Position announcement
42  *    - Abandoned/completed call counters
43  *    - Failout timer passed as optional app parameter
44  *    - Optional monitoring of calls, started when call is answered
45  *
46  * Patch Version 1.07 2003-12-24 01
47  *
48  * Added servicelevel statistic by Michiel Betel <michiel@betel.nl>
49  * Added Priority jumping code for adding and removing queue members by Jonathan Stanton <asterisk@doilooklikeicare.com>
