The audio issue you mention is likely due to resources.  There is no doubt the 
ACD is a resource hog.  Specifically CPU.  Which odd as the rest of sipx seems 
to be more RAM constrained. 
We used to have issues with the choppy audio until we standardized our platform 
with an ODM 3-4 years ago.  The equipment we have used for the last 3-4 years 
has a Dual Core Core2 w/ 8GB of ram and an enterprise Intel SSD.  Its starting 
to get dated but even our largest call centers run well on that.   

I have not had any of the other issues you mentioned.  But I will note we never 
use the "presence" with the ACD.   For us, its not needed.  In a call center, 
the people manning the phones are only their to answer ACD calls.  So unless 
they are on a current queue call....they shouldnt be on the phone.  The ACD 
then doesn't have to worry about subscribing to the presence of each phone.  It 
know when the queue call starts/ends. 

Other than the ACD has been pretty straight forward for us.  Only once in a 
great while do we get the call thats stuck in the call stats and we have to 
bounce the CDR.  I'd say once every 6 months.  But most of our customers get a 
non-acd stuck call in the CDR about once every six months anyways. 

They only consistent change we make to the acd to make it stable is to set a 
local subnet under "internet" for 127.0.0.2  (in fact now we add the entire 
127.0.0.0/24 subnet as local) 
I think 127.0.0.1 is in by default but we cant even pick up queued calls 
without 127.0.0.2 listed.  We discovered that a few years back when 4.2 came 
out....should be a thread on it.  Traces showed the ACD would reference 
127.0.0.2 and not 127.0.0.1 and it would think the call is natted and throw the 
public natted ip in the response. 

But I'm not sure if that is unique to us or not.  We maintain our own builds 
based on SLES so it may be in how we compile.

I am quite impressed with your success stories. :) 



I used to have an ACD running pretty well on a 4.0.2 box. Now, I have some 4.4 
boxes and all kinds of issues. Have you ever faced some of them? 



- Audio issues. People complaining about chopping voice and noise. Indeed, if I 
call the extension directly, without passing through ACD, there's a noticeable 
difference in the audio quality. 



- Realtime statistics - some calls that enter the queue and got picked up never 
"leave" the queue. On sipxacd_events.log one can see the events "enter-queue", 
"pick-up" and "terminate". Sometimes there is the "transfer" event as well. 
Some calls never got the "terminate" event written on that log. Then you have 
on Calls Statistics page calls with +70min long, when the real call took only 
3min.


- Routing to agent: still on the above example, ACD Presence shows the user as 
idle but the ACDServer "thinks" the user is still not free. That agent will 
never get a call again until you restart ACDServer.



- sipxacd.log is full of 
"2012-08-30T18:44:02.139782Z":934039:KERNEL:NOTICE:sip.example.com:MpMedia:B6BB1B90:sipxacd:"OsMsgQShared::doSendCore
 message queue 'mpStartUp::MpMisc.pSpkQ' is over half full - count = 12, max = 
14" 



+1 on what Todd Hodgen said about the best practices/tips. 



Sorry to hijack the thread.

I've often heard it cited that the old ACD cant transfer out of the queue. I 
think this is based on very old info....pre 4.2 days. We have no less than 
hundreds of calls (if not thousands) across several customers sites sending 
calls into queues and back out to non ACD extensions. ACD has preformed very 
well for us and is very stable (i cant think of one ACD related crash/issue). 
When it comes to transferring out of the queue, I'd say our heaviest call 
center customer that has 23 agents and processes no less than 800 calls a day 
will transfer 50% of the calls from and agent out of the queue to a regular 
extension. They even transfer ACD calls back out to external numbers (hairpins).

In fact, we have a customer that has some pretty complex call flow in and out 
of the ACD.
Calls come into the queue. If its not answered it overflows out to an AA where 
they get custom options to keep holding etc. they then get transferred back 
into a second ACD queue. This happens multiple times. Siptraces are quite long 
because each call stays anchored in the queue which is great for reporting.

Hunt groups do not provide was call centers want. Call center managers need to 
run reports based on when an agent signed in/out; how long did they talk; how 
long did they ring; how long are customers waiting in queues and how many 
customers are stacking up in queues....

The distinctive tone as noted in this original thread and modified caller id 
are also part of that need.

Hunt groups just dont preform these functions (if they did, they would be an 
ACD and not a hunt group).

So for us, the bulk of our installations are call centers. As VOIP/SIP becomes 
more common place its increasingly difficult to sell something that just does 
call routing and voicemail...there is just so many cheap and hosted solutions 
if thats all you need. Which is why are installations for the last few years 
have moved up the stack to customers that have more specialized needs.

So for us, our dilemma is get sipXacd maintained internally (we have an elance 
dev working on that now), or look for a new platform.

The problem with the old ACD, every time I tried to use it, was that it was 
fragile. Do this, don't ever do that, etc... Any time I tried to use it in a 
situation the customer (and then ultimately me) had a bad experience. 



If they can make it stable, and make it so you can transfer calls out of queue 
that would be awesome. 



Most people don't need a real ACD (even though they think they want an ACD). 
What they need are fancy hunt groups which is exactly what the 4.4 ACD does. 



Work has begun on a new hunt group app that will hopefully alleviate the need 
for an ACD in cases where it really isn't needed. This will be based around 
some new code and involve a B2BUA that can 'own' the call and then hunt out. 
This will be in contrast to how hunt groups work now where it's a SIP messaging 
nightmare. 



Circular hunt groups, linear hunt groups, being able to ring the same extension 
at more than one point in a hunt group are all envisioned. At some point I'd 
even like to see users be able to (from a phone or user portal) login/out of 
hunt groups, or only ring certain users for different days/hours in a hunt 
group. 



With the current workload I wouldn't expect anything until 4.8 though. 



Thanks, 

Mike

Funny, the beep is one reason my customers wont move to openACD. OpenACD for my 
customers that need a true ACD. The old ACD worked well despite its bad rap.

We have a developer working on get sipXacd ported over to 4.6 so there is hope 
yet.

As to your specific issue, I don't think the tone is an audio file, so you 
would need to create a patch to remove it.

Thanks Tony, one thing that made me go back to 4.4 ACD was the CallerID and 
DNID! In 4.4 ACD when a call arrives; an agent would see a Queue name and the 
Line extention in CallerID but in OpenACD even the DNID changes to agent 
extension number; therefore prevents me from knowing what number was dialed!! 
This was my primary result, do you see this as well?

fyi - If you are referring to the existing ACD (not openacd) I don't think any 
resources are going into it as it is being removed in favor of the openacd 
integration starting up in 4.6.

This could be a very old issue! I was wondering if there is a way to remove the 
beep heard a short moment after an agent picks up a call on ACD!! Thanks.
