Issues with Queue Member Status in Asterisk

Asterisk Asterisk Support
1

Hello,

I am encountering issues with the status of queue members in Asterisk. I’ve noticed that queue members start to show as Not in use after a while, even when they are on an active call at that moment, and this call is being received from the same queue that is showing them as Not in use. I have not yet been able to identify the exact moment when this happens.

For instance, in the contingencia queue, the extension 8032 is showing a status of Not in use:

contingencia has 5 calls (max unlimited) in 'rrmemory' strategy (500s holdtime, 411s talktime), W:0, C:483, A:102, SL:1.4%, SL2:1.2% within 0s

However, extension 8032 is on a call at this moment, and even stranger, it’s on a call that it received from the contingency queue. If I call the extension, it signals busy, and if I check the hints, it shows that the extension is Idle.

Everything was fine at the beggining of the day, but as time passes and the number of calls increases, this starts to happen more frequently with different extensions in the queue.

To make things even stranger, the status was correct for the next call that came in:

contingencia has 3 calls (max unlimited) in 'rrmemory' strategy (231s holdtime, 715s talktime), W:0, C:493, A:114, SL:1.4%, SL2:1.2% within 0s

Has anyone else experienced this?
Do you know how to resolve it or can you provide any guidance on what I should look into?

Thanks.

The chan_sip module is what calculates/determines/provides that information, if it’s not correct then it’s likely something in there.

3

These extensions are connected remotely through VPN.
Could this be happening due to some kind of packet blocking on the network? Any packet being blocked, lost, or discarded?

How could I monitor this?

Is this calculation you’re referring to constantly done during the call? In this case, can this status change during the call, what I mean is, at times it will show Not in use and at others InUse within the same call? Or is this calculation only done at the moment a call is sent to the extension?

I do not remember any details of how chan_sip determines such things or the specifics.

I don’t believe the problem is in the sip settings, I use realtime with a postgres database, and the extension in the example is configured as follows:

# SELECT name, defaultuser, host, type, context, secret, nat, callgroup, pickupgroup, language, disallow, allow, callerid, description FROM public.sippeers WHERE name = '8032';
 name |       defaultuser        |  host   |  type  | context |    secret    |         nat         | callgroup | pickupgroup | language | disallow | allow |             callerid              | description
------+--------------------------+---------+--------+---------+--------------+---------------------+-----------+-------------+----------+----------+-------+-----------------------------------+-------------
 8032 | TESTE TESTE TESTE TESTE1 | dynamic | friend | ddd     | 2ysOIsWBhFI0 | force_rport,comedia | 23        | 23          | pt_BR    | all      | ulaw  | "TESTE TESTE TESTE TESTE1" <8032> | Atento
(1 row)

I have these same settings working on other clients and I’ve never had this problem, what’s different in this one is that their network is very closed and segmented and with many members and many calls happening.

I still need help with this case, it is still happening that an extension that is on a call appears as Idle both in the queue and in the hints, I have already confirmed and in the sip.conf there is the line callcounter=yes within [general].

The problem is still happening very frequently, is there anything I can do to identify where the problem is, does anyone have any idea?
