Overview


Technical Description: 3Com VCX IP Telecom Module x3250m2 - 3CRVH702596C-UK (Networks Network Accessories)

The 3Com IP Telecommuting Module enables remote users to access Session Initiation Protocol (SIP)-based communications services over the Internet. Working in conjunction with existing firewalls, the module provides access to corporate SIP IP communications systems while blocking other protocols. A choice of standalone or DMZ configuration offers flexible connection options. No special hardware or software is required at the user end. This 3Com solution avoids the security risks that can result from the inability of conventional firewalls to recognize SIP dynamic port allocation. The only way to enable these firewalls for SIP traffic is to open the ports, exposing the enterprise network to security risks. The 3Com IP Telecommuting Module, however, provides SIP-aware security by first monitoring SIP signaling protocols as they arrive, then assigning and managing the dynamic addresses by performing SIP proxy and registrar functions. Because the record contains the private IP addresses of users inside the network, a firewall is able to securely relay SIP signaling to the proper destinations through UDP or TCP ports.

Warranty: 1 Year Hardware Repair/Replacement and 90 Days Software Half Replacement


Features


  • Allows remote users full benefit of their enterprise IP telephony system without compromising security

  • Lets SIP clients inside the firewall be reached by a public address while concealing internal IP addresses from the public Internet

  • Enables transparent communication between different networks connected via the Internet without disrupting the existing NAT infrastructure

  • Operates in a firewall DMZ's with all traffic passing through the firewall using static TCP and UDP ports

  • Expedites traffic in a standalone configuration by operating in parallel with the firewall and functioning as an ingoing/outgoing SIP proxy handling only traffic

  • Offers the safety of running on a security-hardened version of Linux
