Therefore, Cisco Jabber will have to communicate through whateverLayer 3 router is configured to route IP packets between the voice and dataVLANs. The PC will likely reside in the data VLAN while the phone will likely reside in the voice VLAN.CAST protocol operates over TCP/IP and uses TCP port 4224 in bothdirections. When the phone is an audio-only phone, Cisco Audio Session Tunnel (CAST) is used to split the audio and video media during video calls so that the audio can be sent through the UC phone and video can be sent through the Cisco Jabber client. Cisco Jabber for Mac in deskphone mode doesn’t support deskphone video. The client uses CCMCIP to gather the information about devices associated with a user and creates a list of IP phones available for control by the client. Deskphone mode creates a CTI connection with Cisco Unified Communications Manager to control the IP Phone. The client uses the CCMCIP or UDS service to get the device name to register with Cisco Unified Communications Manager. Softphone mode downloads the configuration file from the TFTP server and operates as a SIP registered endpoint. Cisco Jabber can register in softphone mode or deskphone mode. The default product mode is one in which the user’s primary authentication is to an IM and presence server. The following figure shows the architecture of an on-premises deployment in deskphone mode: * CAST is only used when the phone is an audio-only deskphone controlled by a Cisco Jabber client You can also provision users with additional services such as voicemail or conferencing. To deploy phone-only mode, provision users with devices for audio and video capabilities. In Phone-Only mode, the user’s primary authentication is to Cisco Unified Communications Manager. – IM-Only: To deployIM-only mode, enable instant messaging and presence capabilities. – Full UC: To deploy fullUC mode, enable instant messaging and presence capabilities, provisionvoicemail and conferencing capabilities, and provision users with devices foraudio and video. You can deploy Cisco Jabber inthe following modes: An on-premises deployment is one in which you setup, manage, and maintain all services on your corporate network.
