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 😀
enough with the reminiscing, here are the affected IP phones:-
- 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
- Cisco Unified IP Phone 7910+SW
- Cisco Unified IP Phone 7910G+SW
- Cisco Unified IP Phone 7912G
- Cisco Unified Wireless IP Phone 7920
- Cisco Unified IP Conference Station 7935

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
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
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
something i noticed while looking through the DRF was the location of the MoH files,

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

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:-

Slp_servreg process causes high cpu utilization on a Unified Communications Manager server.
Problem is observed for IBM model servers only.
This particular defect is applicable to UCM ver 7.x only.
From the command line interface, issue the “utils snmp hardware-agents restart” command. This should resolve the issue. If not, a server reboot may be necessary.
