This patch gives the optional ability to keep queue rules in RealTime. It is
important to note that with this patch:
(a) Queue rules in RealTime are only examined on module load/reload
(b) Queue rules are loaded both from the queuerules.conf file as well as the
RealTime backend
To inform app_queue to examine RealTime for queue rules, a new setting has been
added to queuerules.conf's general section "realtime_rules". RealTime queue
rules will only be used when this setting is set to "yes".
The schema for the database table supports a rule_name, time, min_penalty, and
max_penalty columns. min_penalty and max_penalty can be relative, if a '-' or
'+' literal is provided. Otherwise, the penalties are treated as constants.
For example:
rule_name, time, min_penalty, max_penalty
'default', '10', '20', '30'
'test2', '20', '30', '55'
'test2', '25', '-11', '+1111'
'test2', '400', '112', '333'
'test3', '0', '4564', '46546'
'test_rule', '40', '15', '50'
which would result in :
Rule: default
- After 10 seconds, adjust QUEUE_MAX_PENALTY to 30 and adjust
QUEUE_MIN_PENALTY to 20
Rule: test2
- After 20 seconds, adjust QUEUE_MAX_PENALTY to 55 and adjust
QUEUE_MIN_PENALTY to 30
- After 25 seconds, adjust QUEUE_MAX_PENALTY by 1111 and adjust
QUEUE_MIN_PENALTY by -11
- After 400 seconds, adjust QUEUE_MAX_PENALTY to 333 and adjust
QUEUE_MIN_PENALTY to 112
Rule: test3
- After 0 seconds, adjust QUEUE_MAX_PENALTY to 46546 and adjust
QUEUE_MIN_PENALTY to 4564
Rule: test_rule
- After 40 seconds, adjust QUEUE_MAX_PENALTY to 50 and adjust
QUEUE_MIN_PENALTY to 15
If you use RealTime, the queue rules will be always reloaded on a module
reload, even if the underlying file did not change. With the option disabled,
the rules will only be reloaded if the file was modified.

|
; Look for queue rules in the queue_rules database table through RealTime. Note
|
|
; that this option is not strictly "RealTime", in the sense that the queue
|
|
; rules are only loaded and parsed during module load/reload. Queue rules
|
|
; must have a unique rule name and support relative min/max penalties.
|
|
;
|
|
; realtime_rules = yes
|
|
;
|
|
|
|
; It is possible to change the value of the QUEUE_MAX_PENALTY and QUEUE_MIN_PENALTY
|
|
; channel variables in mid-call by defining rules in the queue for when to do so. This can allow for
|
|
; a call to be opened to more members or potentially a different set of members.
|
|
; The advantage to changing members this way as opposed to inserting the caller into a
|
|
; different queue with more members or reinserting the caller into the same queue with a different
|
|
; QUEUE_MAX_PENALTY or QUEUE_MIN_PENALTY set is that the caller does not lose his place in the queue.
|
|
;
|
|
; Note: There is a limitation to these rules; a caller will follow the penaltychange rules for
|
|
; the queue that were defined at the time the caller entered the queue. If an update to the rules is
|
|
; made during the caller's stay in the queue, these will not be reflected for that caller.
|
|
;
|
|
; The syntax for these rules is
|
|
; penaltychange => <number of seconds into the call>,<absolute or relative change to QUEUE_MAX_PENALTY>[,absolute or relative change to QUEUE_MIN_PENALTY]
|
|
;
|
|
; Example:
|
|
; [myrule]
|
|
; penaltychange => 30,+3 ; 30 seconds into the call increase the QUEUE_MAX_PENALTY by 3, no change to QUEUE_MIN_PENALTY
|
|
; penaltychange => 60,10,5 ; 60 seconds into the call increase the QUEUE_MAX_PENALTY to 10 and increase the QUEUE_MIN_PENALTY to 5
|
|
; penaltychange => 75,,7 ; 75 seconds into the call keep the QUEUE_MAX_PENALTY the same and increase the QUEUE_MIN_PENALTY to 7
