Cisco Unified Communications Manager is the core call control application of our collaboration portfolio. It provides reliable, highly secure, scalable, and efficient enterprise call and session management. More than 200,000 customers worldwide have deployed over 60 million Cisco IP phones and tens of millions of soft clients.

Features and Capabilities


Unified Communications Manager version 11.5 continues to advance the state of the art in mid- and large- size enterprise call control. This release supports evolving Cisco collaboration solutions while adding key functionality such as new features for hybrid services, enhancements for a better user experience, and other improvements for security and compliance.

Hybrid Services

As we continue to extend our offerings into the cloud using Cisco Spark, connecting these cloud solutions to premise-based systems is critical. Call Service Aware and Call Service Connect are two new features that support the hybrid model.

User Experience

Unified Communications Manager 11.5 continues to enhance the user experience with features such as:

  • Enhanced instant messaging user experience using multi-device messaging (carbons) within Jabber, which maintains IM sessions simultaneously across devices and endpoints
  • Improved video quality for low-bandwidth and high-definition environments
  • Unified Communications Manager and Unity pin synch; they now utilize the same PIN

Security and Compliance

Safety is improved through location services. Commujications Manager, working in unison with Cisco Emergency Responder, now pulls a user’s location from Wi-Fi access points.

It also supports next-generation encryption, including:

  • TLS 1.2, AES-256 RSA and ECDSA-based cipher support for SIP and SRTP Interface
  • AES-256 RSA- and ECDSA-based cipher support
  • Latest RSA CryptoJ Library support (6.1.x)
  • 3072 and 4096 RSA Certificate Key Size
