Upon completing this chapter, you will be able to do the following:

  • Describe native presence in Cisco Unified Communications Manager without Cisco Unified Communications IM and Presence (IM&P) servers
  • Describe how the subscribe CSS controls presence watchers
  • Describe how presence groups add more granularity to the presence functionality
  • Describe the requirements when using Cisco Jabber for presence functionality
  • Describe how to integrate a Cisco presence solution within a Microsoft environment in an enterprise
  • Describe the characteristics of the Cisco Unified Communications IM&P OVA templates and the required physical resources
  • Describe the Cisco Unified Communications IM&P cluster architecture
  • Describe how to deploy Cisco Unified Communications IM&P in different scenarios
  • Describe how Cisco Jabber discovers services to register
  • Describe the Cisco Jabber quality of service issues with trust boundaries
  • Describe the different ports that Cisco Jabber uses to communicate
  • Describe how to connect Cisco Unified Communications IM&P clusters within the same domain
  • Describe how to connect Cisco Unified Communications IM&P clusters that are in different domains
  • Describe SIP federations with Microsoft domains
  • Describe the state mappings between Cisco Unified Communications IM&P and Microsoft Skype for Business
  • Describe the preparation that is necessary to implement a federated presence network

This chapter describes the Cisco Unified Communications IM and Presence (IM&P) architecture and design. Native presence in Cisco Unified Communications Manager (CUCM) is presented and the different Cisco Unified Communications IM&P approaches are described. Cisco Unified Communications IM&P can be configured to peer with another Cisco Unified Communications IM&P cluster in the same domain or can be federated with Cisco Unified Communications IM&P clusters in a different domain.

NOTE

The previous name of IM&P was Cisco Unified Presence Server (CUPS) in prior versions of Cisco UC.

CUCM Presence Introduction

This section describes native presence in CUCM without Cisco Unified Communications IM&P servers, as shown in Figure 14-1.

Figure 14-1

Figure 14-1 CUCM Presence

CUCM offers very limited native presence functionality on IP phones. Although a Cisco Unified Communications IM&P server is not required in this simple example, only these native presence features of the CUCM are available:

  • CUCM speed-dial presence: CUCM administratively supports the ability for a speed dial to have presence capabilities via a BLF speed dial. BLF speed dials work as both a speed dial and a presence indicator.
  • CUCM call history presence: CUCM administratively supports presence capabilities for call lists and directories on the phone.
  • CUCM presence policy: CUCM provides the capability to set policy for users who request presence status.
