CUCM Device Packs

I was running a DX80 with a CE firmware load but the lab CUCM we had installed did not support the CE Version of code, when i first tried registering the endpoint to the CUCM it came up with the following error: Failed: 485 Ambigious / Device Type Mismatch,i had a look at CUCM to see if the device load was installed but only the “Cisco DX80” endpoint was available. This is the Android version of the DX which is not the same as the ‘Cisco TelePresence DX80’ you see on the web browser of the endpoint.

for this you need to install the relevant device pack to get the ball rolling and endpoint registered.

These notes are applicable on the following versions but tested for 10.5(2)

  • Unified CM 11.5(1)
  • Unified CM 11.0(1)
  • Unified CM 10.5(2)
  • Unified CM 9.1(2)

Step 1: Verify the CUCM Version you are running

From web browser > About

ccm version

you can also get this information from the web browser:

Step 2: Download the Appropriate Device Pack

Install a the relevant device pack for the endpoint that you wish to configure on the CUCM, in this case the DX80 is not a ‘native endpoint in cucm as such a device pack will need to be installed:

Device Type Device Release Unified CM 11.5(1) Unified CM 11.0(1) Unified CM 10.5(2) Unified CM 9.1(2)

Please note:

  • A valid cisco support contract will be needed
  • Device package compatibility matrix is located here


Step 3:  Upload Device pack to CUCM

3a) in OS Administration under  >  Software Upgrades > Installation/Upgrade > Chose the Remote File system where your device pack is located.

3b) verify MD5 hash with downloads page where you installed the file from

Step 4: Restart TFTP Service

Control Center – Feature Services > Cisco Tftp > Restart

Step 5: Install Phone

now if you go to add new phone (device>phone) or go to device defaults (Device> Device Settings>Device Defaults) you will see the new device types:

Cisco TelePresence DX70
Cisco TelePresence DX80



Death to the phones of old

As of CUCM version 11.5 Cisco has finally removed support for the legacy phones, now when i say Legacy i mean really old phones.. i understand why theyve removed its support and have always been impressed on why they have had these in for so long. They make some really tough phones, I remember visiting a customer site with a really intense call center and phone usage. they had 7940’s IP phones whose key pad was completely worn out but the phones were just slogging away.the customer saw no need to replace the perfectly functioning IP Phones. I dont think this customer will be upset that Cisco has made this announcement because they are not affected

… but i will surely be 😦 i have a 12SP phone, one of the first IP Phones from the Selsius days that i managed to get from a friend @ cisco. i still use it from time to time but looks like i will be adding it to my museum with great regret .. if i decide to upgrade 😀

  • Cisco IP Phone 12 S
  • Cisco IP Phone 12 SP
  • Cisco IP Phone 12 SP+
  • Cisco IP Phone 30 SP+
  • Cisco IP Phone 30 VIP
  • Cisco Unified IP Phone 7902G
  • Cisco Unified IP Phone 7905G
  • Cisco Unified IP Phone 7910
  • Cisco Unified IP Phone 7910G

Cluster Manager service connectivity test

Dec  10 12:04:54 AXD-SUB1 local7 6 : 2432: Dec 10 12:04:54.257 UTC :  %CCM_CLUSTERMANAGER-CLUSTERMANAGER-6-CLM_PeerState: Current ClusterMgr session state. Node’s Name or IP:AXD-PUB Node’s State:POLICY_INJECTED App ID:Cisco Cluster Manager Cluster ID: Node ID:AXD-SUB1

noticed the above notification in the CUCM syslog every few minutes. This is a connectivity test performed by the CUCM cluster manager service to the Publisher . This is a unecessary alert as there is no policy state change.

This can only be stopped by a TAC Engineer, the process is as follows:

1) Create a TAC user account

admin:utils remote_account enable
admin:utils remote_account create ciscotac 30

2) on the Subscriber stop the Cluster Manager Service

admin:utils service stop Cluster Manager
Service Stopped
Cluster Manager [STOPPED]

3) Cisco TAC will apply the following command in root to disable cluster manager notification:-

[root@AXD-SUB1 ~]# /usr/local/platform/bin/clm/clm_ctl set clm_network_test_timer 0

4) restart the service cluster manager service

admin:utils service start Cluster Manager
Service Started
Cluster Manager [STARTED]

This Service may cause drop outs on the phone system, and best done out of hours. It takes a few minutes (more like seconds) to complete. Continue reading

Bouncy Castle .. All childs play

i was having a look through the DRF log files into why they failed, and noticed Bouncy Castle service inserted to the security paameters, amused by the name, i googled it….. nothing special, its just a bunch of API’s used in cryptography and used by Java and C#

2011-12-02 09:45:45,472 DEBUG [main] – drfNetSSLManager: initSecurityProvider:  Bouncy castle provider inserted into list of Security Providers

accessing the Core dump File

This section forms part of my diagnosis on a failed subscriber and the identification onto why it failed, The CUCM creates a core dump file when it experiences a fault.

This can be found on the RTMT Alert central and the Application Event log:-

 Nov 30 00:19:35 BMML-SUB1 local7 2 : 0: Nov 30 00:19:35.810 UTC :  %CCM_LPM-LPMTCT-2-CoreDumpFileFound: The new core dump file(s) have been found in the system.
