I was going in the same direction at the end of my first mail, but I
hadn't written any code. There is a problem though: The Queue
application will keep sending calls to the Local channel, which have to
be rejected, over and over.
Would it perhaps work to simply Wait(30) if the call is rejected by the
phone? If the Queue assumes that the phone is busy for those 30 seconds,
I have accomplished my goal. It's worth a shot.

If the Queue assumes that the phone is busy for those 30 seconds, I have accomplished my goal. It's worth a shot. This works! Actually I tried out Wait(1000), but that worked fine. After 30 seconds (the timeout in the queue) the Local channel was closed, and a short while later a new call attempt was made. Just as I was hoping. It would still be neat to have a min_dial_interval option, so that Queue never overwhelms the server with failing dial attempts. /Benny ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Queues with unavailable members
That shouldn't be too hard to accomplish. If you've got the addons (and mysql) installed you could store them in a MySQL table (timestamp, device) and have a cron job set to run at X frequency that un-pauses the queue members via AMI. Don't want to go to MySQL? Use system() to 'touch' files named after devices. Then have your cron script go through the files by creation date. Either way gets you there. -Elliot -Original Message- From: Benny Amorsen [mailto:benny+use...@amorsen.dk] Sent: Thursday, October 15, 2009 5:06 AM To: Elliot Otchet Cc: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: Queues with unavailable members Elliot Otchet elliot.otc...@callingcircles.com writes: Have you tried autopause=yes in your queue configuration?

Perhaps the problem could be restated in a different way: After a queue member rejects a call (instead of just not answering), the queue should wait X amount of time before sending the next call.

To pause an agent, store the unpause time per agent in the AstDB.
Then when you're deciding whether to give out a call (in the Local
channel), look up ${DB(AgentPaused/agentid)} and compare it to the
current time. If there is no record or the time has passed, put the
call through; otherwise, skip that agent.
Sorry, no example code yet... I just wanted to get the idea out there.

You could configure them as agents and have them log off automatically after a while they're not responding. l. 2009/10/14 Benny Amorsen benny+use...@amorsen.dkbenny%2buse...@amorsen.dk We have the possibly rather unique setup where we have cell phones posing as SIP devices. The SIP registration for those unfortunately doesn't go away just because the phone is off, since the registration is done by our cell-phone=SIP gateway, and that gateway has no way of knowing whether the phone is on or off. This is usually ok, but it gets problematic if the cell phone is a member of a queue. In that case Queue() keeps sending the call to the phone, and the cell-phone=SIP gateway dutifully makes a call, which is then rejected by the cellular network. A few seconds later, Queue() tries again. This needlessly wastes resources both in Asterisk and in the cellular network. One idea is to run the call through chan_local (we do this anyway because we need to format the caller-ID differently for different phones) and then record if a call is rejected, and for the next 30 seconds just abort if we are asked to send a call to that particular phone. The downside is that we are still running a call through part of the dial plan, but at least it can be done in perhaps 3 lines of code. I would very much like to hear about smarter ways to do it. /Benny ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users -- Loway - home of QueueMetrics - http://queuemetrics.com ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
