Subject: [asterisk-users] Realtime Call Queues : call members in certain order

Hello,

I'm using MySQL realtime Call Queues (table queues and table queue_members).

I would like to ring the members of the call queue in a certain order. Therefore I use ring strategy lineair and I put the members into the table queue_members in the order in which they have to be rang.


So I have the queue :

| name           | musicclass | announce | context | timeout | monitor_type | monitor_format | queue_youarenext | queue_thereare | queue_callswaiting | queue_holdtime | queue_minutes | queue_seconds | queue_lessthan | queue_thankyou | queue_reporthold | announce_frequency | announce_round_seconds | announce_holdtime | announce_position | retry | wrapuptime | maxlen | servicelevel | strategy | joinempty | leavewhenempty | eventmemberstatus | eventwhencalled | reportholdtime | memberdelay | weight | timeoutrestart | periodic_announce | periodic_announce_frequency | ringinuse |

and queue members :

| uniqueid | membername     | queue_name     | interface          | penalty | paused |
+----------+----------------+----------------+--------------------+---------+--------+
|       44 | queuemem4  | queue6 | SIP/queuemem4  |       0 |   NULL |
|       45 | queuemem2  | queue6 | SIP/queuemem2  |       0 |   NULL |
|       46 | queuemem5  | queue6 | SIP/queuemem5  |       0 |   NULL |
|       47 | queuemem1  | queue6 | SIP/queuemem1  |       0 |   NULL |
|       48 | queuemem10 | queue6 | SIP/queuemem10 |       0 |   NULL |
|       49 | queuemem18 | queue6 | SIP/queuemem18 |       0 |   NULL |
|       50 | queuemem17 | queue6 | SIP/queuemem17 |       0 |   NULL |
|       51 | queuemem12 | queue6 | SIP/queuemem12 |       0 |   NULL |
|       52 | queuemem16 | queue6 | SIP/queuemem16 |       0 |   NULL |
|       53 | queuemem13 | queue6 | SIP/queuemem13 |       0 |   NULL |
+----------+----------------+----------------+--------------------+---------+--------+



You can see that the member queuemem4 is first in line to be rang (has the first and lowest uniqueid in the table).

But the first member that is being rang, is queuemem1. How come ??


Kind regards,

Jonas.

Jonas,
We encountered the same problem. It is a bug in the Queue application. The Queue application actually orders members by their interface value. Here is the bug report I opened https://issues.asterisk.org/jira/browse/ASTERISK-18480 which was closed as "Not A Bug" by Digium.  We worked around this by prepending an integer (001__, 002__, ...) to the interface in the database table and then removing it later in the dial plan. Hope this helps.

Hello,

thank you for your reply.


Is it the "membername" or the "interface" that needs to be sorted to have a certain order in the call queue ?


How do you remove the prefix (integer) from a call queue member from dialplan ?

If you call the queue in your dialplan as follow :

exten => s,n,Queue(${queuename},,,,${timeout})

How can you "edit" its members ??



Kind regards,

Jonas.

Jonas,
When asterisk queries the database for queue members it sorts the results based on the value of the interface column.  We use local channels for calling agents (i.e. Local/001__agent at queue_calling/n) so your mileage may vary. To strip off the prefix we have the following in our queue_calling context.
[queue_calling]
exten => _XXX__[A-Za-z0-9*#].,1,Goto(${EXTEN:5},1)
exten => _[A-Za-z0-9*#].,1,...
... Logic to call the agent's SIP phone ...
