IP Coral Sentinel

New voice and video services over the LAN and WAN allow small offices, branches or employees working from home to seamlessly communication. Unfortunately, the protocols used to enable these services conflict with two of the most notable network security mechanism: Firewalls and NATs.

To overcome the restrictions of firewalls and NAT, the Coral Sentinel brings the intelligence to allow an organization to install a Coral IP-based system in a firewall or NAT environment. With Coral Sentinel, personnel at corporate headquarters and remote offices, as well as home users and travelling employees, can all be part of a single seamless telephony over IP network, with no damage to network security. The Sentinel performs NAT transversal, allowing users to move freely even with DHCP.
