CVP and CUCM Sizing

Dear Community members
Reading SRND for CVP 10.5 I found the following thing (page 57):
calls delivered to the Cisco Unified Communications Manager cluster should be load-balanced
among the subscribers in the cluster and should not exceed 2 calls per second (cps) per subscriber.
So, If I need IPCC with 15 CPS, I will need 8 Subs + 8 backup subs? And does it mean that it should be call-processing subs?
As CUCM SRNS says:
A Unified CM cluster may contain as many as 20 server nodes, of which a maximum of eight call
processing subscribers (nodes running the Cisco CallManager Service) are allowed
Does it mean I can have only 16 CPS for one CUCM Cluster?
Thanks in advance

A standard CUCM cluster can only have 8 call processing subs, a mega cluster can have 16, but that requires Cisco BU approval and is rare deployments. 16 cps is actually pretty high, are you expecting to go beyond that in your deployment? If so you may need to deploy multiple CUCM clusters.

Is there a way to script finding users in Unity and CUCM

I currently get a list once a month of all users who no longer work for our company. As we roll out more VOIP installs the list grows and the old way of doing things needs to change. Currently I search one by one through CUCM and Unity to see if the user is assigned a phone. I would like to be able to pull a list of all users from both Unity and CUCM put that into a spread sheet and then compare my attrition spread sheet to that spread sheet therby speeding up the process of determining which users might be assigned a phone.
Note company hires warehouse workers and they come and go frequently and are not assigned phones but, they along with users with phones are all dumped into a spread sheet so I have no way of know who is who.
1. I have a spread sheet with names on it both people with and without phones
2. I would like to download a list so I can compare the two and determine which ones have phones
I am open to other ideas and suggestions to make the laborious task easier.
Thank You in advance

Seems easy enough on the face of it - unless there's something I'm not getting - are you talking Unity or Unity Connection (folks often just say "Unity" as shorthand for either) - if you're dealing with Unity then you'll have to dance with ODBC which isnt' the end of the world but doing it from "script" is going to be a challange. If you're talking about Unity Connection you can also use ODBC but you have the option for an HTTP REST search for users by name.
So it's just a matter of searching by name and getting matches back (names are not guranteed to be unique of course, assuming you mean name as first/last/display name and not alias). It can kick out all matches I suppose and include the extension number. Unity and Unity connecton _always_ have extension numbers (it's required) so I'm unsure what someone "without a phone" would look like in Unity/Connection - that's a bit odd - how do they check messages? And without a phone why do they have a voice mail account?

Exchange 2013 SP1 and CUCM 9.1.2 - Exch not recognizing called extension

I think I'm almost there in getting Exchange 2013 SP1 UM working with CUCM 9.1.2...I've got two issues at the moment that I need a little help with.
1) When I dial my VM pilot (6040) from a UM enabled extension it prompts to enter an extension. When I dial the same extension and let it ring to VM, Exchange picks up and says "the person you are trying to reach does not have a valid voice mail box
on our system".
2) This just started happening this afternoon, when I dial my VM pilot (6040) exch3 picks up as thats what I have my route pattern pointing to. If I enter the extension of a mailbox on exch2, I get stuck in a endless loop.
I've followed this post as a guide but it hasn't resolved my issue.
https://supportforums.cisco.com/discussion/11914031/exchange-2013-um-and-cucm-86
My Exchange environment looks like this:
Site 1:
exch1 - CAS/Mailbox, used for mainly utility type work, journal, dedicated SMTP flows etc
exch2 - CAS/Mailbox, part DAG13
exch3 - CAS/Mailbox, part of DAG13
Site 2:
exch2dr - CAS/Mailbox, part of DAG13
exch3dr - CAS/Mailbox, part of DAG13
DAG13 is stretched between two sites, there are no users at our DR site so CUCM is pointing to Site 1 for UM. Each site has an internet facing CAS-only server for OWA/EAS etc.
Any help is greatly appreciated. I'd love to get rid of Unity.
EDIT:
I just found this event in the event logs:
The Microsoft Exchange Unified Messaging service on the Mailbox server received a diverted call with ID "d51600-3a3140c5-9b8-c1414ac@EXCH3-IPADDR" for extension "4099" on UM dial plan "CUCM" from UM IP gateway "CUCM IP",
but no UM-enabled mailbox for the corresponding extension could be found. Please check the extension and make sure that the corresponding mailbox is enabled for UM and associated with the correct UM dial plan.

9.1.2 I think it is, we upgraded to avoid the known DNS bug
I cant see how to PM you either
The crux of it was outlined below with some tweaks
http://blogs.technet.com/b/canitpro/archive/2014/04/30/step-by-step-integration-between-exchange-2013-um-and-cisco-unified-communication-manager.aspx
As we have multiple combined role servers, our trunks are set up as follows:
1. 1 x CAS Trunk - contains all CAS Servers on port 5060
2. 4 x MBX Trunks - contains Maibox Server with ports 5062-5068
On top of that, we had to Allow "Redirecting Diversion Header Delivery - Inbound (and Outbound)" on the CAS Trunk but DISABLE it on the Mailbox Trunks
Also, make sure that you are using Telephone Extension Dial plans in Exchange 2013 (Despite them being unable to be associated with a 13 Server - EX13 answers for all calls anyway)
Lastly, the MS documentation is a little strange - it says that as your last step of UM migration, you should point your Call Manager to 2013 - I don't agree with that statement, EX13 routes calls back to 2010 UM Servers perfectly fine, so treat it the same
as any other CAS based service - point to 2013, and it will handle the rest

Can not foward into voicemail from outside call on CUE and CUCM 8.6

Dear Team,
I have CUE Utility and CUCM 8.6.
I can call from local, if user busy or go out office then call will foward to voice mail.It is ok.
But when i call from outside to my phone(direct line), then call can not foward to voice mail on CUE.
Please help me some solution.
Thanks.

Hi nam,
A couple of things to check. Have you set the Forward Busy/No Answer "External"
on the DN config page in CUCM?
Are the calls coming in using a codec other than g.711?
Best Practices for Deploying Cisco Unity Express
• Each mailbox can be associated with a primary extension number and a primary E.164 number.
Typically, this number is the direct-inward-dial (DID) number that PSTN callers use. If the primary
E.164 number is configured to any other number, use Cisco IOS translation patterns to match either
the primary extension number or primary E.164 number so that the correct mailbox can be reached
during SRST mode.
• Each Cisco Unity Express site must be associated with a CTI route point for voicemail and one for
AA (if licensed and purchased), and you must configure the same number of CTI route points as
Cisco Unity Express ports licensed. Ensure that the number of sites with Cisco Unity Express does
not exceed the CTI scalability guidelines presented in the chapter on Call Processing, page 8-1.
• Cisco Unity Express is associated with a JTAPI user on Cisco Unified CallManager. Although a
single JTAPI user can be associated with multiple Cisco Unity Expresses in a system, Cisco
recommends associating each dedicated JTAPI user in Cisco Unified CallManager with a single
Cisco Unity Express.
• Calls into Cisco Unity Express use G.711 only. Cisco recommends using a local transcoder to
convert the G.729 calls traversing the WAN into G.711 calls. You can configure Cisco Unified
CallManager regions with the G.711 voice codec for intra-region calls and the G.729 voice codec
for inter-region calls.
• If transcoding facilities are not available at the Cisco Unity Express site, provision enough
bandwidth for the required number of G.711 voicemail calls over the WAN. Configure the Cisco
Unified CallManager regions with the G.711 voice codec for calls between the IP phones and Cisco
Unity Express devices (CTI ports and CTI route points).
• The CTI ports and CTI route points can be defined in specific locations. Cisco recommends using
location-based call admission control between Cisco Unified CallManager and Cisco Unity Express.
RSVP may also be used.

UCCX and CUCM Upgrade

Hi All - We are planning to go for CUCM direct upgrade from 7.1.3 - 9.1.2
Also for UCCX from 7.0.1 SR5 ---> 8.5.1 --> 8.5.1 SU3 --> 9.0.2
During upgarde of UCCX 8.5.1 on UCS Machine it will ask to eneter CUCM AXL user Credentails which is in 9.1.2, So we need to know is that correct way by doing so since UCCX is 8.5.1 and CUCM 9.1.2
Also i checked few PDF'S where i can get below info.
These Unified CM versions are supported - 8.0(1), 8.0(2) and all SUs, 8.5(1) and all SUs, and Unified CM 8.6.2.22033 and later.
Does it mean CUCM 9.1.2 is compatible with UCCX 8.5.1 and 8.5.1 SU3.
SIVANESAN R

Refer to this document for all CCX compatibility details including which version you can upgrade from:
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_compatibility/matrix/crscomtx.pdf
CUCM 9.1.2 is compatible with CCX 8.5SU4 for example.
Also, you can upgrade to CCX 9.0.2 directly from 7.0.2ES3.

Cluster setup and APS sizing

Hi,
I have 2 windows servers here with BI 4.0 SP2 installed on each of them and I have clustered the two CMS. Now, in CMC, I see 18 servers each for each node - so total of 36 servers that are running and enabled. ( I am talking about APS, AJS, CMS, IFRS, OFRS, dashboard servers etc.....). My questions are:
1) Should I leave them all enabled and running at all times ? my understanding is that I should, because that is how the load balancing and failover will happen. But at a couple of forums, I have read that some people leave the servers of one node off.
2)I read in some forum that by clustering the two bobjs on two servers, basically only the CMS is being load balanced. Is that true ?? Does this mean that other servers like APS, AJS, Dashobard server, crystal server and the corresponding services within them are not really being load balanced even though both are running at the same time ?
3) My installation is default and we havent gone live yet. I havent really created or modified any of the servers like APS etc. but I am reading that in your production system, you should create multiple APS servers and distribute similiar services among them ? is this true ? Note # 1580280 and the sizing companion for BO 4.0 talks about it too.Should i really worry about this even if I am only going to have 100 users in production ?
Thanks,
Jason

1) Should I leave them all enabled and running at all times ? my understanding is that I should, because that is how the load balancing and failover will happen. But at a couple of forums, I have read that some people leave the servers of one node off.
You should stop and disable all default APS and AJS servers and then create Specific APS/AJS servers only with services that you need.
There are several KB's on APS issues in BI4 and most are resolved with splitting them up.
Non APS servers you should stop those that are not part of your reporting requirements.
2)I read in some forum that by clustering the two bobjs on two servers, basically only the CMS is being load balanced. Is that true ?? Does this mean that other servers like APS, AJS, Dashobard server, crystal server and the corresponding services within them are not really being load balanced even though both are running at the same time ?
That is not true. When 2 BI4 nodes are clustered , over time the load of each service is balanced.
3) My installation is default and we havent gone live yet. I havent really created or modified any of the servers like APS etc. but I am reading that in your production system, you should create multiple APS servers and distribute similiar services among them ? is this true ? Note # 1580280 and the sizing companion for BO 4.0 talks about it too.Should i really worry about this even if I am only going to have 100 users in production ?
Yes, the default APS are not good at all and should never be used in the production, even if you only have 5 users

Cannot make outside call (H.323 gateway and CUCM 6)

I cannot make outside calls. I am using H.323 gateway configuration and CUCM 6. I have attached configuration file and debug file. I configured H323 gateway and route pattern in CUCM. Please let me know if this is a configuration issue or telecom issue.

Hi 9tysixuae,
I can see that call is hitting the analog ports but from there on it generates error 34 which means circuit not available. You can try the following :
1. Plug Analog phone and verify if the circuit is fine ?
2. Try putting signal ground start on the voice port and see if that makes any difference.

Capacity planning and hardware sizing

Hi,
I would like to know in detail about capacity planning and hardware sizing while deploying oracle database products. I need to know about properly planning the infrastructure and configuring and deploying the products. Moreover, when should we use RAC,how many nodes, exadata, DR etc. How to size hardwares RAM,Disk for this kind of implemetations.
I know it depends on budget and environment. Still if anyone kindly give some links/docs I will be able to have a decent start in this domain.
Regards,
Saikat

See , they all depend on your company policy and the database size that they are going to have.
1. Size : i have worked on databases sizing from 80G to 2000G , all depending on the client or the industry you are catering to.
2. hardware and Ram : Server Team should know this better , you can have a simple small server if the DB and application are small and the usage would be less. If it a full fledged system with high load then you need to get in touch with your server team and raise an oracle SR for exact specifications for that database and also plan for some future growth.
3. RAC : depends on the project if it requires such a setup.
4. DR : is for disaster management. Also all companies implement this by adopting data guard ( physical standby).
5. For having a good start , start reading the books and refer to oracle documentation. More you refer , more knowledge you will get .
Start with the basics.... make your basics strong.. and then move ahead with complex setups.

CUCM 6.1 DirSync and CUCM trash collector program

If I turn on DirSync and CUCM syncs LDAP data to CUCM but I then turn off DirSync before the trash collector program runs will my original user data be there in the CUCM corp directory?

Peter,
Right on.
So what you are saying is that if I enable DirSync and allow the sync to happen and I don't like the results I can disable DirSync before the garbage collector program runs and my original CUCM User database data will be available again?
The main thing I was trying to determine is if DirSync is enabled and the actual sync process happens does it permanently alter my CUCM User database at that point even before the garbage collector program runs.
Somebody pointed me to the correct documentation for "Cisco Unified Communications Solution Reference Network Design (SRND)
Based on Cisco Unified Communications Manager Release 6.x"
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/6x/uc6_0.html
It includes some really thorough information on LDAP Directory Integration.
I am currently reading through the details.
Man I wish I had found this from the start it would have saved me a lot of time and questions! :)

CUEAC 9.1.1.10 and CUCM 7.1(5) 64 bit TSP Plugin

Hello,
I have a customer with CUCM 7.1(5) who has purchased CUEAC 9.1.1.10 and wants to run it on Windows Server 2008 R2 (64 bit).
According to the data sheet this should be supported but when I go through the CUEAC server installation process it tries to download the 64 bit TSP plugin from the CUCM server.
This is a problem as CUCM 7.1(5) does not have the 64 bit TSP plugin - it only has the 32 bit version.
The exact message I get is
Error occured while downloading Cisco TSP.
Path: https://10.80.20.12/plugins/CiscoTSPx64.exe
I have obtained the 64 bit TSP from a later CUCM and done a manual installation hoping that the installer would see the TSP is already installed and skip the step but it does not do so.
Can anyone suggest how to resolve this?
I know I could use a 32 bit version of Windows Server or upgrade CUCM but these options are not available.
Thanks

Update
I built a CUCM 9.x server as a virtual machine and integrated CUEAC with that. The 64 bit TSP downloaded and installed ok and I was hoping that I could then reconfigure the TSP CTI manager addresses and the CUEAC CUCM server to point to the version 7.1 CUCM server.
Unfortunately this did not work as I got a message complaining about version incompatibilities between the CUEAC server and CUCM.
I do not think there is any workaround for running CUCM 7.1 with CUEAC on a 64 bit Windows Server.
Luckily for me the customer found an old Windows 2003 32 bit server that they used to run Cisco ACS on. CUEAC installed without a hitch on this server and is running fine.
If anyone manages to get this working I would be interested to know how.
Lesson here is do not believe Cisco data sheets

NAT between IPIVR (or UCCX) and CUCM?

Hi,
i would like to know if NAT between IPIVR (or UCCX) and CUCM is allowed? (with ASA only or also router and switch).
I didn't find anything about it in UCCX SRND.
thanks
[IPIVR v8, CUCM v7.1(5).]

Hello,
1) Yes, please use sip trunk as the interface between cme and cucm.
2) Please note: officially cme sip trunk video is only supported for cme1—sip trunk---cme2 type set up, but for basic call you could try to setup cucm to use early media on the sip trunk. cme by default would use early media and it should work.
3) For configuration guide on CME Video, you can refer http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmevideo.html#wp1027101
4) For interfacing CME with CUCM, please remember to configure below command on CME:
       voice service voip
        sip
          asymmetric payload full
Hope this helps,

UCCX and CUCM issue

Hi,
I integrated UCCX 8.5 and CUCM 8.5 in a lab setup using VMware.
Created CTI ports and then some applications including AA application. But when calling from my soft phone to the Trigger, its getting disconnected after 5 seconds. I am not able to hear the prompt also.
Checked and started all the services and resynced all the applications and finally installed CUCM and UCCX again but still the same issue is happening.
Please give some valuable inputs.
Regards..

Hi
You should probably try a debug of the script. Run Script Editor and make sure you log in. The do Debug/Reactive Script, and enter SSCRIPT[aa.aef] in the top box, and 60 in the bottom box.
Then dial the AA.
One of several things should happen:
1) Nothing at all - in this case the system can't run the AA script, and you'll have to look at the logs to find out why.
2) The script will appear, and you can step through it by pressing F10 and see what the script does in real time. As you step through the steps, if you go past a Play Prompt and still get silence, then it might reach a point where it decides you aren't responding and hangs up on you
3) You might get an error in the script
Report back what happens...
Also:
1) What language configuration do you have on the system?
2) If you press the ? key on a 79xx twice quicky during the 5 second call, do you see rx packets increasing?

Cucme and cucm with aim-cue

Hi all, I just want to know if AIM-CUE can work with cucme and cucm 8.0?
Because based on this matrix Cisco Unity Express Compatibility Matrix [Cisco Unity Express] - Cisco Systems
It says that it is supported, but CUE (AIM-CUE Module) should have a version of 7.2 or 7.3 to support cucme 8.x and cucm 8.x
Can anyone confirm this because aim-cue is the cheapest among the CUE cisco offers. Thanks!

That's what I read, having cue 7.2 or 7.3 will let you use cucme/cucm 8.x
When you say "there will not be any new firmware release on the old aim-cue", Does that mean that cue version 7.3 will be the last firmware version to be released on the old aim-cue that will support cucme/cucm 8.x? Future versions of cucme/cucm (version 9) will not be supported by the old aim-cue?

Lifecycle Workflow platform and database sizing guide?

I've been asked to investigate the technical aspects of the Lifecycle Workflow and Reader Extension products.
I've gone through the various adobe websites a great deal and found installation guides but nothing that provides platform selection and database sizing recommendations.
We are considering both JBoss on Suse LInux and WebSphere on AIX as a platform.
Is anyone aware of any recommendations as to the choice of a platform?
Any experiences or recommendations out there from the user community?
Also, is there any documentation that gives guidance to database sizing? Frankly, I'm not sure I understand yet whether it's just the routing/metadata that gets stored in the workflow database or the actual documents as well.
Anyone point me at or provide me more technical documentation?
Thanks
Verlyn

Hi Verlyn
I can answer some of your questions, based on my understanding.
The workflow engine does store the document itself as part of the workflow. In fact, it records the historical state of the document at each point that someone in the workflow worked on it. You can see this by looking at the "Participated" item in Form Manager, where you can see the historical value of each form that's been submitted. Any workflow attachments are also stored in the database.
It gets a little more complicated. Depending on how you structure your workflow, you can choose to either store the entire PDF (in a document or binary variable) or just the data (in a form variable -in which case the data is merged with an xdp template whenever someone wants to view it).
Document variables are also a little more intelligent: you can specify a size threshold. Below that threshold, the document is stored as a blob in the database - above the threshold, the document is stored in a folder on the file system. The default threshold value is 64K.
I hope this helps...
