CUCM 11.5 Released – Warning!

CSR (CUCM/IM&P/CUC) 11.5 has been released!  It includes a lot of cool new features but there’s a warning that needs to be shared for customers who have legacy phones.

New Features of note:

CUCM 11.5

  • “Hitless” Device Pack Installation.  Add new device types without an immediate reboot.  TFTP restart required, and Publisher reboot at next maintenance window.
  • Read-only AXL user role.  (Finally!)
  • PIN Sync to Unity Connection
  • User-customizable  Display Name field searchable in the directory for users who want a nickname or short name.  (e.g. Mike White vs Michael White — both searchable)
  • Directory search for MRA clients/devices
  • UCM Scale Increase with same OVA spec
  • Single SAML SSO Agreement per Cluster
  • Next Gen Encryption (DOD Suite B)
  • VMWare ESXi 6.0 support, Single SAML IdP per Cluster

 

IM&P (Jabber Server) 11.5

  • Multi-device Messaging.  Finally copies of chats messages are sent to all clients, not the most recently active.  Read notifications sync’d across all devices.
  • Persistent Chat HA and support for MS SQL (in addition to currently-supported Postgres and Oracle) for Persistent Chat functions.

Unity Connection

  • Full video messaging.  In addition to video greetings, video messages can be left in inboxes.  Video playback is supported from the handset, and not Jabber at this time.  (This functionality requires Mediasence as the video engine.)
  • PIN Synchronization between CUC and CUCM
  • New Media Player replaces the old MediaMaster applet
  • Support for Exchange 2016/Outlook 2016, Windows 10, MS Edge Browser
  • Next Gen Encryption (DOD Suite B)
  • VMWare ESXi 6.0 support, Single SAML IdP per Cluster

 

The warning is located in the release notes.  Certain legacy (i.e. REALLY OLD 12+ year EoS models) phones WILL NOT WORK with CUCM 11.5.

Update: A Field Notice has been posted.

This is a drastic change from previous versions were the phones are no longer supported and may not work properly anymore rather than disabling these models.  For example, I have an old 12SP+ at the office and it would register to CUCM 10, but not really work right.  In the case of 11.5, IT WILL NOT WORK.

Realistically the only models that I still see customers with are the 7935 Conference Station, 7920 Wireless, and 7910.

If you have these endpoints, understand that most have been EoS for over 12 years, and that there is a very aggressive phone trade-in program to get 20-30% extra discount (on top of your normal discount) to go to the new 8800 series phones.

Deprecated Endpoints

As of Cisco Unified Communications Manager Firmware Release 11.5, the following phones are not supported:•    Cisco IP Phone 12 SP+ and related models
•    Cisco IP Phone 30 VIP and related models
•    Cisco Unified IP Phone 7902
•    Cisco Unified IP Phone 7905
•    Cisco Unified IP Phone 7910
•    Cisco Unified IP Phone 7910SW
•    Cisco Unified IP Phone 7912
•    Cisco Unified Wireless IP Phone 7920
•    Cisco Unified IP Conference Station 7935

If you use any of these phone models on an older release of Cisco Unified Communications Manager and you upgrade to Release 11.5, the phone will not work after the upgrade completes.

Here’s an example from my CUCM where I have a 7905 defined.  The phones stays there, but this giant warning appears at the top.
