With the HP VCX x3250M2 IP Telecommuting Module, home office workers, traveling employees, and other authorized users can securely access their company IP telephony system over the Internet, taking advantage of a wealth of communications applications utilizing the Session Initiation Protocol (SIP). Because SIP dynamic port allocation is not recognized by conventional firewalls, the only way to enable these firewalls for SIP traffic is to open the ports that will be used by that traffic. Unfortunately, this action exposes the enterprise to security risks. To mitigate these risks, the HP VCX IP telecommuting module provides SIP-aware security by first monitoring SIP signaling protocols, such as SIP registration and session establishment, as they arrive over the Internet. The module then assigns and manages the appropriate dynamic addresses of users inside the network, and the existing firewall is able to relay SIP signaling to the proper destinations through its UDP or TCP port.
