asterisk users - Jul 2005 - A problem with queues

Hello,

I am implementing a small call center with 1 to 4 agents.

For some reason I don't understand, if an agent is busy, and it is his/her
turn in the queue round, asterisk gives an "all destinations are busy"
message and hangs up the call. Agents are SIP lines registered with an
audiocodes MP108FXS which registers each line independently. Ringing strategy is
RoundRobin (most of this configured using AMPortal, but checked that is
consistent with documentation on queues on the wiki).
Supposedly, the roundrobin strategy is used on available agents, not busy ones,
am I correct ? Where can the failure be ?

The best way I was able to replicate the problem is using only two agents, one
received a call that stayed on for several minutes, the second received another
call that waqs a short one, and the third call did not reach the second agent as
it wanted to reach the first agent (per roundrobin) and failed. I was expectin
it to ring again on the second agent.

Regards,

Jorge A.

I'm assuming you are using Agent based queues... If so, in your dialplan 
what happens after your Dial with the timeout?  Is this timeout greater 
than the queue timeout?  If so I've seen this behavior on my system.  My 
solution, always make the queue timeout less than the dial timeout.
