Hi all,
I am trying to implement an alert system, which should call a couple of phones as long as somebody accepts the alert (e.g. by entering # or something along these lines).
I tried the following setup:
- I created a call file and put it in the outgoing spool directory:
Channel: Local/s@alert
Callerid: Nagios
MaxRetries: 10
RetryTime: 60
WaitTime: 600
Extension: s
- the alert context in extensions will put the call into the alert_queue
[alert]
exten => s,1,Queue(alert_queue|tr|||600)
exten => s,2,Hangup-
exten => t,1,Playback(vm-goodbye)
exten => t,2,Hangup
- the alert queue ist setup like this:
[alert_queue]
music = default
strategy = rrmemory
;announce = queue-alert-info ; tells the member how to acknowlege the call
timeout = 90
wrapuptime=30
announce-frequency = 0
announce-holdtime = no
joinempty = yes
member => local/s@alert_member
For testing purpouses there is only one member right now, but obviously in deployment there will be more
The call will then be handed to the alert_member context, this should provide the acknowledge functionality. Numbers are hard coded etc, this sill needs work.
[alert_member]
exten => s,1,Dial(sip/sipgate/12345678)
exten => s,2,Playback(tt-somethingwrong)
exten => s,3,Background(for-yes-press)
exten => s,4,SayDigits(2)
exten => 1,1,Goto(s,2)
exten => 2,1,Goto(alertack,s,1)
exten => t,1,Goto(alert,t,1)
[alertack]
exten => s,1,Playback(thank-you-cooperation)
exten => s,2,Playback(vm-goodbye)
exten => s,3,Hangup
When I put the call file into the outgoing queue, I get the following console output:
Attempting call on Local/s@alert for s@:1 (Retry 1)

…
The flow works as expected, but even if I pick up the phone asterisk keeps on trying to call the member. Why would it do that?
I don’t understand a couple of things:
-
when will the call file be cleared? Once I put it into the Queue? Or do I need to call Answer before? (I tried this, but still multiple calls will be made)
-
how does the queue command work? I don’t know where the control flow goes once I called queue. I sort of circumvented this by explictly calling the local/alert_member context from the queue.
Maybe there is a better / easier way to achieve what I want to do.
Any help is very much appreciated.
Thanks
