Cisco Jabber Login Flow

Posted on by

This topic shows the login flow of Cisco Jabber registering with Cisco Unified Communications Manager.

Registering process of Cisco Jabber with Cisco Unified Communications Manager:

First, Cisco Jabber queries the DNS server for the service records, which is not shown in the figure. If Cisco Jabber is on the corporate network, the local DNS should reply with the _cisco-uds server record to provide the location of Cisco Unified Communications Manager (version 9.0 or higher) or with the _cuplogin server record to provide the location of Cisco Unified Communications IM and Presence Service.

Cisco Jabber uses the Cisco Unified Communications Manager IP Phone (CCMCIP) profile to receive a list of available devices that are bound to the user that is logging into Cisco Jabber. After receiving the device list, the user can select a device if more devices are configured.

Then, the configuration file is requested from the TFTP server. After reading out the configuration file, the device registers using SIP messages, as shown in the figure.
