Call Queue ring all not ringing all phones

[dkhileman]

I have recently deployed a new Switchvox to a customer and they use a queue to ring all phones simultaneously each time a call comes in. The problem is that all phones will not ring at all times. It seems that random phones will not ring for one call and then will ring for another.

What could be causing this?

I'm assuming this is a ring-all call queue? Not a round robin/ etc.?

If they are permanent members, I'd check the setting "Seconds for Wrap Up".

My guess is that some extensions are "wrapping up" after taking a call, thus not ringing when a new call comes in.

Thanks for the info. I set the wrap up time to 0 but it still appears to be happening. Any other suggestions that I can try?

Hmmm.

Have you rebooted the phones (what model phones are you using)? Also, what firmware/software version of Switchvox are you running? When's the last time the PBX was rebooted?

[jonbayless]

Just to clarify, all the phones are either permanent members or are logged in to the queue in question, right? 'Ring all' means ring all members active in the queue, not 'ring all the phones attached to the system'. Also, it is possible the phones might be set to do not disturb or have a ring rule for queue calls to not ring or forward, etc.

How many members do you have in this ring all call queue, and on which Switchvox appliance is your PBX running?

Im actually having the same issues. Our ring all queues have a max of 9 users, which I did notice was the limit. We experience very weird behavior. One minute all the phones will ring and the next time only 5 will ring. We also seeing an issue where a phone will ring from the queue and a user will be going to pick up the phone and it will stop ringing on that extension and begin on another extension within the queue.

Extremely weird behavior that we are not able to put our fingers on. I'm hoping someone has an answer this is getting to be out of control.

You hadn't posted the software version you're running yet, but I did want to mention something similar...hope it helps. Mine was on r5.5.4, and we had one phone that was a permanent member of the 'Ring All' call queue, but it would NOT ring (all the other ones would); we went to Server/System Reload, and clicked the top item (Software Reset I think it was called...the one that does NOT cut off calls) and that cleared it up, where all phones would ring again.

Often, we have found that the 'top' System Reload button doesn't clear up the glitches, but the second one down (Software Restart I believe, unless I've got the 2 names mixed up...don't have it in front of me right now) DOES...however, it does drop calls, so use with caution.

This is interesting... is there really a limit of 9 phones in a ring-all queue? I've heard similar reports of not all phones ringing (and we probably have something like 100+) but hadn't verified that it wasn't just someone having their ringer turned down or some other "user error" situation.

If there is a limit, is it really only 9? and if you have a queue with a much larger number of phones, how does it "decide" which ones to ring if not all? is it just the first X exts in the queue, or random or ???

we've got an AA335 on Switchvox 5.5.5

[Josh_E]

There is no hard-coded limit to the number of extensions that you can have in a ring all call queue. This means there is also no logic in the system to determine which will ring and which wont.

That being said, depending upon the hardware you're running your PBX on and the overall load of the system, there is is a practical limit, which, when exceeded can cause performance issues.

However, 9 members in a ring call queue should be well within the limits of the AA355 even on a moderate to heavy stress system.

Are the members setup as Login members? Are they logged in?

[hiltonmw]

There definitely were some weird queue oddities with older versions of the software... 5.5.5 seems pretty stable though. we've got call queues (ring-alls) on 355s with 10-15 users in them and it doesn't break a sweat and works as expected. That being said, they are doing almost ZERO call recording and ZERO conferences, etc. So, the overall load on the system is low.

There aren't hard-limits on the number of phones in ring-alls groups, but what others have said is true - there are non-hard limits so if there's other concurrent calls happening, paging, and/or call recordings you could have issues.

Any updates on this? Did you open a ticket with Digium?
