Deprecated Cisco IP Phones in CUCM 14

Remember this mess with several tens of Cisco IP phones available on the market (not counting video endpoints)?
There were:

  • old-school 7900 series,
  • intermediate 6900, 8900 and 9900 models,
  • newly introduced 7800 and 8800 IP phones,
  • finally some experiments like 3905, Android-based DX650 etc

So these times are over.

For the past couple of year Cisco step by step cleaned up the IP phones portfolio: In Cisco Unified Communications Manager 11.5 they deprecated 7902, 7905, 7910, 7912, 7920, Conference Station 7935.
The following models were deprecated in Cisco UCM 12 - wireless IP Phone 7921, 7970 and 7971.

And now the MAJOR CLEANUP is coming with Cisco Unified Communications Manager, Release 14 affecting CUCM 14, Cisco BE 6000 / 7000.

Just take a look. The phone models to be deprecated in Release 14 are:
- Cisco Unified SIP Phone 3911
- Cisco Unified SIP Phone 3951
- Cisco Unified IP Phone 6911
- Cisco Unified IP Phone 6921
- Cisco Unified IP Phone 6941
- Cisco Unified IP Phone 6945
- Cisco Unified IP Phone 6961
- Cisco Unified IP Phone 7906G
- Cisco Unified IP Phone 7911G
- Cisco Unified Wireless IP Phone 7925
- Cisco Unified Wireless IP Phone 7925G-EX
- Cisco Unified Wireless IP Phone 7926
- Cisco Unified IP Phone 7931
- Cisco Unified IP Conference Station 7936
- Cisco Unified IP Conference Station 7937G
- Cisco Unified IP Phone 7940
- Cisco Unified IP Phone 7941
- Cisco Unified IP Phone 7960
- Cisco Unified IP Phone 7961
- Cisco Unified IP Phone 7985
- Cisco Unified IP Phone 8941

If you are using any of these phone models and you upgrade to Release 14, you will not be able to use these phones after the upgrade.

After you switch over to CUCM 14, registration of these phone models will be blocked.

So, better check the phones you use and plan the migration to 7800 and 8800 series in advance.

Enabling Cisco UCM CDR Collection

Yes, CUCM can collect CDR (Call Detail Record). This article will show you how to enable this feature (disabled by default).

Enabling CDR

Open Cisco Unified CM Administration interface:

Proceed to System → Service Parameters and select the following parameters:

  • Server — select the node to be manipulated,
  • Service — select Cisco CallManager (Active).

In the Parameters section that appears, find System and select:

  • CDR Enabled Flag * — True. This parameter indicates the call manager to create and store CDR records for each call passing through this UCM;
  • CDR Log Calls with Zero Duration Flag * — True. Enabling this parameter makes the server save the unsuccessful calls and calls that were shorter than 1 second (helpful for troubleshooting).

Don’t forget to apply the changes. Repeat this actions for each node in a cluster (if you have more than one server in System → Service Parameters → Server menu).

Additional configuration

Now let’s explore advanced parameters. On the configuration toolbar, click Advanced:

Select the following options:

  • Call Diagnostics Enabled – Enabled Only When CDR Enabled Flag is True. This parameter switches on so-called Call Management Records (CMR), which are very helpful for troubleshooting;
  • Display FAC in CDR – True. This parameter indicates whether Forced Authorization Code (FAC) should be displayed in CDR. Generally, this parameter depends on your security policies. We chose to display it;
  • Show Line Group Member DN in finalCalledPartyNumber CDR Field – True. Briefly, this parameter shows DN (directory number) of the group member that answered a call, instead of the group’s number;
  • Show Line Group Member Non Masked DN in finalCalledPartyNumber CDR Field – basically, the same as the previous one.

Open Cisco Unified Serviceability page, proceed to Tools → CDR Analysis and Reporting section. Now you can select CDR tab to use Search or export the data. Enjoy!
