/mcpRecommended Deployment Cisco Unified Communications Manager (Unified CM) is the call control server for the Cisco Collaboration on- premises Preferred Architecture. Cisco IP Phones, Jabber clients, and TelePresence video endpoints use SIP to register directly to Cisco Unified CM. The Unified CM cluster's failover mechanism provides endpoint registration redundancy. If a WAN failure occurs and endpoints at remote locations cannot register to Unified CM, they use SRST functionality for local and PSTN calls, but some services such as voicemail and presence might not be available. We recommend the endpoints listed in the following tables because they provide optimal features for this design. Cisco has a range of endpoints with various features and functionality that an organization can also use to address its business needs. Table 2.
