How can I make Asterisk keep track of dynamic SIP agent statuses?

  • 772

I am setting up a new server using Asterisk 1.8.11-certified4. In testing, we're seeing that agents dynamically logged into the queue will receive a second queue call as a call-waiting when call-limit is set to 0.

Since the agents in question are not always in the agent queue, call-limit=1 would unnecessarily prevent them from receiving call waiting even when they're out of the queue.

The test and result from the below configs were as follows:

  • Had remote user login to queue
  • Placed call into queue
  • remote user answered call #1
  • placed call #2 to queue
  • remote user reported the second call came in as a call-waiting.

context enter-sales-queue {
        s => {
                Answer();
                Queue(den-x-queue,,,,60);
                Voicemail(9001,u);
                Hangup();
        };
};

    I asked the same question in the Asterisk IRC channel on freenode, and one of the developers responded indicating that in newer asterisk versions (I assume 1.8 and above) you need to specify callcounter=yes in your general config of sip.conf.

    He also mentioned that call-limit should never be zero, as that is not technically a valid option for that field. It should be 1 or greater.

    In versions of asterisk prior to 1.8, callcounter=yes does not exist, so simply specifying a call-limit with an arbitrarily high number will cause Asterisk to track the number of calls properly and make the queue function as expected.

    IF ASTERISK 1.8 OR LATER:

    sip.conf

    
[general]
callcounter=yes

    IF ASTERISK PRIOR TO 1.8:

    sip.conf

    
[exten]
type=friend
...
call-limit=999

  2. This may help:

    Following reports from several Asterisk users that they're having problems with ringinuse=no not working when Local Channels are used to provide hot-desking support within the Asterisk Queue() function, we have developed a very easy fix for this that is now documented in our popular Asterisk Queues Tutorial.

    You don't need to do anything fancy with STATEINTERFACE to get this to work, and it also works with all Asterisk phone types, including SIP and DAHDI channels.

    For further details please see:

    http://www.orderlyq.com/asteriskqueuesLocal.html#ringinuse

    So, if you're struggling with this, perhaps as a result of abandoning the now-deprecated Agent Channel mechanism, you might want to take a look :)

    [edit] This requires using OrderlyStats and setting the Auto-Pause parameter in the Admin section to >0 [\edit]
