Re: [asterisk-users] Capture queue agent drop and put caller back in queue
2013/1/21 Mitch Claborn mitch...@claborn.net Asterisk 11 Occasionally we will have a partial power outage, or a piece of network equipment will fail, and our queue agents who are on active calls with callers will be disconnected from the caller. What I'd like to do is capture those calls and put them back in the queue (at a high priority) so that we don't lose the caller. I've tried to duplicate the situation in my lab: I have one agent in the queue, a caller dials into the queue, gets connected to the agent then I pull the ethernet cable out of the agent's computer (testing with a softphone) but I don't see anything happen on the asterisk console. core show channels shows the 2 channels still bridged even though the agent is gone. Shouldn't asterisk somehow know when the agent disappears? How can I accomplish my goal? I am not sure that from the PoV of the caller this solution would work - they would experience tens of seconds of silence plus they would have to go back to the queue. If this happens rarely, you could have a process call them back instead - you acknowledge what happened and have someone on-line with the person apologizing. We have a few clients implementing something like this for calls exiting the queue on timeouts and it seems to be well-liked by the callers. Of course it depends on what you are doing and the level of service that callers come to expect. Just my two cents, l. -- Loway - home of QueueMetrics - http://queuemetrics.com Test-drive WombatDialer beta @ http://wombatdialer.com -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Mitch Claborn mitch...@claborn.net writes: Shouldn't asterisk somehow know when the agent disappears? You are a bit out of luck since SIP session timers, the obvious solution, cannot be set lower than 90 seconds. rtptimeout set to e.g. 10 seconds may work, but you need to then set rtpholdtimeout higher and hope that voice activity detection or mute does not kill the calls... Does Asterisk consider RTCP packets for the purpose of rtptimeout? That could solve the problems of silence suppression and mute. /Benny -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Since nobody seems to have come up with an Asterisk-specific solution, it sounds like the real approach here is something more generic. You can set up Nagios to fire off an event if it detects endpoints or infrastructure are suddenly dead. In particular, Nagios could launch a program written for this purpose, passing the endpoints it detects are missing, and that program could then query Asterisk via AMI about the call IDs each endpoint is a participant in, then do a forced-transfer to a dedicated queue that announces the failure condition to the caller. This AMI could also conveniently remove the dead endpoints from the existing queues (including the failover queue). The wildcard here is obviously the program itself, which would be slightly complex. It would have to have intimate knowledge about your infrastructure. It's unlikely something like this currently exists that you can just drop-in, but I'm sure there's someone on this list that would be willing to sell you the labor to write it. -- -Chris Harrington ACSDi Office: 763.559.5800 Mobile Phone: 612.326.4248 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Not doubting how quickly Nagios can respond, but if the Nagios solution is going to place a call using Asterisk, wouldn’t it be just as efficient (or more so) to depend on Asterisk?

My suggestion of Nagios was only to avoid re-implementing the detect device has gone out to lunch code. Obviously the part interacting with AMI is still custom and always will be.

Un-topposted Eric Wieling ewiel...@nyigc.com writes: Using qualify=10 ? qualifyfreq=10 is fine, but Asterisk will not AFAIK do anything to a call just because the peer goes unreachable qualify-wise. You are still stuck with running a script that listens to qualify-unreachables and does the appropriate thing to the calls. It is doable and a valid solution, but not something I would be very happy with personally. I still think that rtptimeout is the appropriate solution. Combine it with the g option to Dial, and you can redirect the call wherever you want. The problems are still: can it be made safe against mute and silence suppression, and does HANGUPCAUSE or similar get set to a useful value when a call is hung up due to rtptimeout? /Benny -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
