Cisco Expressway is an advanced collaboration gateway, that helps solve multiple problems. It works with Cisco Unified Communications Manager, Cisco Business Edition, and Cisco Hosted Collaboration Solution to help make collaboration universal. Extend office connectivity to on-the-go and home office employees. Cisco Expressway makes collaboration as easy to use outside the enterprise as it is inside, by simplifying the end-user experience. Using highly secure mobile access based on Transport Layer Security (TLS), Cisco Jabber mobile users can access all their collaboration workloads (video, voice, content, instant messaging, and presence) without the extra step of establishing a VPN. Cisco Expressway also supports single-sign-on capabilities for Cisco Jabber users, integrating directly with the enterprise authentication and authorization methods in place. Both these capabilities help provide mobile experiences simply from anywhere, on a range of devices with Cisco Jabber clients, and they complement common IT department BYOD security policies. In addition, Expressway makes it easier for teleworkers to use their Cisco endpoints. Workers gain simplified provisioning, configuration, and registration of these devices, as well as the ability for these users to connect from their home office without having to establish a VPN connection.
