CUCM 12: What’s New?

Recently Cisco has released the 12th version of Cisco Unified Communications Manager. In this article, we’ll tell you about 5 main features included in the 12th release.

Mixed (Hybrid) Installation Support

It’s 2018, and cloud solutions are getting more and more integrated into business, becoming a part of infrastructure race. Cisco keeps up, with its unified communication solutions being based on a cloud platform named Cisco Hosted Collaboration Solution (HCS).

It’s important to notice that the 12th CUCM release supports mixed architecture, so a CUCM instance deployed on a company’s own servers and a CUCM instance in a cloud can communicate with each other without any complications.

This architecture helps to perform internal calls in the corporate environment where the CUCM instance is deployed.

Unsupported phones

Planning to upgrade to CUCM 12? Note that the following phones won’t be supported since 12.0:

  • 7905
  • 7970G
  • 7921G
  • 7935
  • 7902
  • 7910
  • 30 VIP
  • 12 SP+
  • 7912
  • 7920
  • 7971G-GE
  • 7910SW

New Licensing Technologies

CUCM 12 doesn’t support the traditional Product-Activation Key (PAK) licensing technology. Instead, Cisco runs Smart Software Licensing, with licenses being associated with a Cisco account, not with a specific device.

IPV6 Support

The 12th version makes it possible to have IPv6-only PBX installation.

TLS Version Definition

What TLS should be used? Which version is safer? This topic tends to be arguable. Cisco engineers decided to end this holy war. With CUCM 12, you can choose which TLS version to use for selected UC devices to communicate: TLS 1.0, 1.1 or 1.2.
