Cisco CIMC - The maximum number of user sessions has been reached

I somehow ran into a "The maximum number of user sessions has been reached" error when working on a new Cisco BE6000 / UCS C220 chassis install.  I had previously updated all the chassis software using the Host Upgrade Utility so I imagine it may have somehow been just me. 

To fix things you can SSH to the CIMC address and run:

show user-session

To change to a particular session from the resulting list, note the session index numbers from the user-session list and run:

scope user-session sessionindex

To end the session you just switched to, run:


To exit the scope of that session, run:

Cisco 8900 9900 slow response time and Simplified New Call UI

We recognized a bizarre issue during post-implementation support recently.  All 8961 series phones were very sluggish and they couldn’t keep up with the receptionists' fast fingers.  After investigation / research, we saw that “Simplified New Call UI” was set to “Disabled” on the root of the phone configuration.  The purpose of this feature is described below.  This was introduced in CUCM 9.x and carries through to the present Collaboration System Release.  After enabling the Simplified New Call UI” on all 8961s in the environment, response time was much faster.  Note that the same applies to the 9951 and 9971 series phones as well. Cisco Bug Tracker appears to indicate there are several related and open issues with the current firmware.

Simplified New Call Bubble
The Simplified New Call Bubble feature provides a simplified window for the user to place an off-hook call. The administrator enables or disables the feature in the Phone Configuration window using the Simplified New Call UI field. By default, the feature is disabled.
When the user start dialing a call with the Simplified New Call Window, the phone does not display possible phone number matches from the call history.
The feature is supported on the following SIP phones:

  • Cisco Unified IP Phone 8961
  • Cisco Unified IP Phone 9951
  • Cisco Unified IP Phone 9971 

Monday, August 11, 2014 Disney PhotoPass downloaded images on your PC

If you visit any of the Disney parks, at least in the USA, you have the opportunity to have your photos taken at interesting locations around the park by Disney's professional photographers.  This is a nice service, as you don't need to worry about finding someone to take your photo if your tired of the "selfie" look, they take multiple photos with good cameras so you will certainly find one you like, and you don't have to waste your time or energy taking photos when you should be enjoying the park.

When you are done with your visit, you can visit to review your photos and purchase the ones you like.  You can pick various print sizes and finishes, and even apply some fun effects.

For those of you interested in how their website works, here's a little information on how to find the photos you review on your local Windows PC.  These cached photos left behind from the website are likely no where as good as the ones you purchase, so I suggest you really just purchase them.  Disney provides a great vacation experience and the photographers a valuable service.

Here I'm using Mozilla's Firefox browser version 31.0 and Microsoft Windows 7.

1. Log into or like usual.
2. Navigate to the page where you can download your photos.

3. In the Firefox menu bar, click the Menu icon (looks like three horizontal bars)
4. Then choose Options.
5. Then choose the Advanced button.
6. Then choose the Network tab.
7. Under Cached Web Content, click Clear Now button

8. Click OK to close the options form.
9. Click some photos that interest you and make them as large as possible.

10. Open a new tab in Firefox, enter about:cache?device=disk in the address bar and hit Enter.

11. Click one of the links with the larger data sizes.

12. The path next to file on disk: i.e. C:\Users\rmaslanka\AppData\Local\Mozilla\Firefox\Profiles\rfsuwz4l.default\Cache\0\D6\EE8A1d01 is where one of the photos you previewed is stored on your PC.
13. To prove it, open a new tab in Firefox and paste that path in the address bar.  You should see just the photo, outside of the Disney website.

14. If you want, you can right click the picture, choose Save Image As and choose a file name and location to save the image somewhere else.

Cisco Jabber using BAT Bulk Administration to add devices

Add Devices

If you have CUWL licensing, you can add Jabber devices for Windows, iPhone, Android and Tablet for each user without additional licensing, assuming each user will have 10 or fewer devices when your done.

You can put your file together in any fashion you like, but I choose to export users via BAT and use that as my reference material for the rest of the files. In CUCM, navigate to Bulk Administration | Users | Export Users.  With that file output, Excel functions are your friend and it's fairly easy to create the following file.  Use something like ="CSF"&$C2 for device names, something like =&C2&" ,"&D2&" - "$E2 for descriptions, etc.

The format you are looking for is something like:

CSFJONES,"Jones, Jim - JONES",1111,"Jones, Jim - JONES","Jones, Jim - JONES","Jones, Jim - JONES","Jones, Jim - JONES","Jones, Jim - JONES",,,716433XXXX,JONES
CSFSMITH,"Smith, Joe - SMITH",1112,"Smith, Joe - SMITH","Smith, Joe - SMITH","Smith, Joe - SMITH","Smith, Joe - SMITH","Smith, Joe - SMITH",,,716433XXXX,SMITH

Then Bulk Administration | Phones | Insert Phones | Specific Details to add devices of each type.

User / DN association

You need to associate users with DNs to enable phone presence information, and because this association is device specific, you are going to need a row for each device that the DN appears on.  If your user had a phone and now has four Jabber devices, that's five rows per user.  Excel is your friend again. 

Create a pivot table with your user export data. Select USER ID, CONTROLLED DEVICE 1 thru CONTROLLED DEVICE 5 (or whatever you need) and TELEPHONE NUMBER as row labels. Go to the USER ID Field Settings | Layout & Print and remove the Display labels from next field in the same column check.  Now you will be pretty close and need to copy each user down four rows.  Ultimately you are looking for a format like:

User ID,Device,Directory Number,Partition
JONES,SEP00260B5D3D2A,1111, AllLines
SMITH,SEP00260B5E4169,1112, AllLines

Upload the file as User Line Appearance, and then Bulk Administration | Users | Line Appearance | Update Line Appearance to associate users to DNs.

User controlled devices

A user needs to have CTI control over the new devices.  Again, use the user export data as your baseline and use some Excel text concatenate functions to populate the CONTROLLED DEVICE 2 through CONTROLLED DEVICE 5.  Use the ="CSF"&$C2 type of function.

Then Bulk Administration | Users | Update Users | Custom File to add control of devices to users.

Cisco UCCX DRS / Backup Status Stuck

Ran into an issue where user was not monitoring the drive space available on their SFTP server / DRS backup target and ultimately filled the drive.  Unfortunately UCCX doesn't care when attempting scheduled backups how much space is available and ultimately backup will fail.

What's worse is checking the DRS backup status and finding a backup in progress from days or weeks ago.  UCCX gives you a pleasant Cancel Backup button to press, but that may result in a infinite Cancelling Backup status loop, refreshing every 5 seconds.


SSH to the UCCX, Primary first if you have HA.  then run:

utils service restart Cisco DRF Master

wait for that to complete and then run

utils service restart Cisco DRF Local

If you have a second HA server, repeat the process there.

The good news is this is not business impacting.
