Communications Deployments
Communications Deployments
Overview
Businesses of all sizes are migrating to IP telephony in order to take full advantage of unified
communications. Cisco
®
Unified Communications products can help businesses streamline their
operations, increase employee productivity, optimize business communications, and enhance
customer care. Because protecting a unified-communications-based network from attacks is
crucial to maintaining business continuity and integrity, Cisco has built security features into its
Unified Communications products, and augments this security with the Cisco ASA 5500 Series.
The Cisco ASA 5500 Series is a family of multifunction security appliances for small businesses,
branch offices, enterprises, and data center environments. These appliances deliver market-
leading voice and video security services for unified communications, including robust firewall, full-
featured IP Security (IPsec) and Secure Sockets Layer (SSL) VPN, intrusion prevention, and
content security features. For unified communications deployments, these platforms can protect up
to 30,000 phones and deliver application inspection for the broadest range of unified
communications protocols, including Skinny Client Control Protocol (SCCP), Session Initiation
Protocol (SIP), H.323, Media Gateway Control Protocol (MGCP), Computer Telephony Interface
Quick Buffer Encoding (CTIQBE), and Real-Time Transport Protocol (RTP) and Real-Time
Transport Control Protocol (RTCP).
Cisco ASA 5500 Series Unified Communications Features
Cisco ASA 5500 Series Adaptive Security Appliances are designed to secure real-time unified
communications applications such as voice and video. The Cisco ASA 5500 Series can be used to
protect all of the critical elements of a unified communications deployment (network infrastructure,
call control platforms, IP endpoints, and unified communications applications). The Cisco ASA
5500 Series delivers several security features that complement the embedded security within the
unified communications system, providing additional layers of protection. These include:
Dynamic and granular access control to prevent unauthorized access to unified
communications services
Threat protection for the unified communications infrastructure
Network security policy enforcement to create and administer effective unified
communications policies for applications and users
Service protection to help ensure maximum uptime for unified communications applications
Voice and video encryption services that enable customers to maintain their security
policies while encrypting signaling and media to prevent eavesdropping. Voice and video
encryption services using SSL/IPsec VPN are also available for extending unified
communications to remote users
