Mobile and Remote Access Through Cisco Expressway Deployment Guide

Mobile and Remote Access Overview

Mobile and Remote Access Overview

Cisco Unified Communications Mobile and Remote Access is a core part of the Cisco Collaboration Edge

Architecture. It allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging and presence services provided by Cisco Unified Communications Manager (Unified CM) when the endpoint is not within the enterprise network. The Expressway provides secure firewall traversal and line-side support for Unified CM registrations.

The overall solution provides:

■

Off-premises access: a consistent experience outside the network for Jabber and EX/MX/SX Series clients

■

Security: secure business-to-business communications

■

Cloud services: enterprise grade flexibility and scalable solutions providing rich WebEx integration and

Service Provider offerings

■

Gateway and interoperability services: media and signaling normalization, and support for non-standard endpoints

Note that third-party SIP or H.323 devices can register to the Expressway-C and, if necessary, interoperate with

Unified CM-registered devices over a SIP trunk.
