             Summary: Asterisk Community  Queue member stays “In Use” after parking a call
                 Key: ASTERISK-27325
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27325
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_parkandannounce
    Affects Versions: 13.17.0
         Environment: OS: CentOS 6.7
Kernel: 2.6.32-573.22.1.el6.x86_64
Asterisk version: 13.17.0
Hardware: Dell PE R200
            Reporter: Andres Miedzowicz

Call parking is configurated in Asterisk 13.17.0 (using PJSIP) using the default settings in res_parking.conf and features.conf. When a call enters a queue and the agent that picked up the call parks it, the status of that agent stays "In Use" until the call ends even though the agent is no longer involved in the call at all.

For example, a call from Alice gets into a queue and gets answered by Bob. Bob parks the call and gets removed from the bridge. After that, Charlie picks up the parked call and talks to Alice normally. During this call, the status of Bob is "In Use" which doesn't allow him to get new calls. Only when the call between Alice and Charlie ends does Bob become available again.

Example: Extension 681 calls the queue and it’s picked up by extension 687. The call is then parked by 687 and picked up by extension 689.

My configuration is the following:

extenensions.conf

include => parkedcalls

[myqueue]
exten => s,1,Verbose(“Entering the Queue”)
same => n,Queue(myqueue,k,30)
same => n, Hangup()

queues.conf

[myqueue]
member => PJSIP/111,Agent Name

features.conf

[featuremap]
parkcall => #7

res_parking.conf

[default]
parkext => 700
parkpos => 701-705
context => parkedcalls
parkingtime => 120

Before placing the call:

asterisk-lab*CLI> queue show test
test has 0 calls (max unlimited) in ‘ringall’ strategy (0s holdtime, 52s talktime), W:0, C:7, A:0, SL:14.3% within 0s
