All agents hearing beep

Hi,

I’m having this problem that just appeared with no apparent reason: every time an agent gets a call they hear the announcement saying he has a call, which is normal, the rare thing is that when any agent gets the call and the announcement, all of the other agents will hear this ‘beep’ like announcing that someone got a call.

Is this something in the configuration or what?

I’m running on this:
CentOS release 5.6 (Final)
Asterisk 1.8.15.0 built by root @ Earendil on a x86_64 running Linux on 2012-08-09 13:51:39 UTC
Loway QueueMetrics - 13.04.2 (Which shouldn’t be any problem for the PBX performance)

Thanks in advance.

Check your Strategies in queues.conf, maybe you have Ringall
