asterisk users - Nov 2010 - Short rings for extensions when part of the Queue

Hi Everyone,

We have three different Queues set to "leastrecent" strategy and from
time
to time I hear someone complain that they receive short rings (partial ring
cycle) and since it's not their turn even if they pickup the phone the call
is not given to them since the Queue is actually hitting someone else at the
same time.

Is this short ring an indication of some sort for "leastrecent"
strategy.
Like maybe you are next in turn or something?

It's annoying and odd that I don't see a pattern to it. If it's a
feature
please let me know.

Using Asterisk 1.4x

Thanks

We have the same issue, and I think I've figured out what's causing it,
by watching the SIP debug output.  

What I noticed is that when someone misses a call on the queue, it
switches over to the next person, but almost immediately (after a short
ring) it breaks off and cancels that call because of a timeout.  I
think it's a matter of timing between the different timeouts you can
set in queues.conf.  I haven't had time to tweak it yet, so that's all
I can tell you.  I don't know how hard it would be to get the timeouts
to jive perfectly, but I'm sure it can be done.

Mind you, this is based on only one observation, so I may be
wrong...  It's only a minor annoyance, and I have bigger fish to fry
right now.  Speaking of which, one of them is almost burnt, so I have
to go. ;-)

I'd be interested to hear your findings...

What do you see in the asterisk console when this happens?

Thanks,

Sorry, I am not following. If an extension rings for 15 or 16 seconds and
then waits for 2 or three seconds what difference does the being divisible
make?

Is there something internal to Asterisk that makes the Retry time dependent
on Time Out (also known as Ring Time)?

P.S. I think the 15 seconds is just three rings complete.

Thanks,
Bruce
