asterisk users - Nov 2005 - Idle time between agent ringing too long

Hi,

I'm using * 1.0.9 with a queue which:
- does not have holding time, position announcement, whatsoever, beside that
- retry = 0 (zero timeout between retries)
- timeout = 24
- wrapuptime=0
-strategy=leastrecent

Agents login by AgentCallbackLogin which registers agents to their SIP
phones at some agent extension which looks something like:
[ext-agents]
exten => _X.,1,Dial(SIP/${exten},300,trM(answercall))
exten => _X.,2,Goto(h,1)
exten => h,1,NoOp

Here's the problem! Each agent phone will ring for about 24 secs
(which is fine), but it takes roughly 5 sec for * to ring the next
agent. Why does it take * too long between retries? Is it due to my
dialplan or * itself? In the latter case, does * 1.2.0 solve that
problem?

Any suggestions/solutions?

Rgrds,

H.
