etc thus, extending the rich media services beyond the boundaries of the enterprise. Cisco Expressway
Series consists of Cisco Expressway-E and Cisco Expressway-C.
Figure 4. Business to Business Collaboration
Cisco Expressway-E acts as a traversal server and allows secure communication through to your business
and provides other services, such as DNS SRV lookup.
Cisco Expressway-C acts as the traversal client for Cisco Expressway-E (required in all Cisco Expressway
E deployments). It acts as a video gateway providing interworking with third party industry standard H.264
SVC, H.323, AVC devices & systems (including Microsoft Lync 2013).
In this design, you create separate traversal zones one for mobile and remote access and for business-to-
business video communications.

Cisco Unified Border Element (CUBE)

Cisco Unified Border Element (CUBE) is Cisco's session border controller (SBC) helping enterprises
connect to Service Provider SIP trunking services. CUBE provides session control, security, interworking
and demarcation to interconnect unified communications networks and enable end-to-end voice.
Deploying CUBE is essential for routing voice calls beyond the enterprise through the IP PSTN to
customers and partners. With SIP Trunking, CUBE lowers costs, simplifies the network and extends rich
collaborative services.
Cisco Adaptive Security Appliance (Cisco ASA)
This design uses Cisco Adaptive Security Appliance as the security appliance. The appliance is deployed in
three-port firewall mode, in which one port is connected to the inside network, another to an outside
interface, and the third to the DMZ interface. Cisco Expressway-E is connected to the DMZ interface of
Cisco ASA. Expressway-C and other collaboration components are on the inside of the Cisco ASA
