Edgewater Networks has added VoIP survivability features to its EdgeMarc line of VoIP CPE appliances. The new functionality provides local call switching in the event of wide area network (WAN) link failures, softswitch failures or during periods of network congestion that result in a loss of connectivity to the softswitch. Edgewater provides the ability to detect a loss of connectivity to the softswitch, a fallback mode of operation offering station-to-station calling for locally connected subscribers and automatic recovery of call control to the softswitch once connectivity has been restored. http://www.edgewaternetworks.com/
- In April 2004, Edgewater Networks introduced a line of session border controllers providing specialized security, NAT/Firewall traversal services and passive call quality monitoring for service providers. These systems provide topology hiding, dynamic session admission control and stateful packet inspection to secure critical VoIP and data infrastructure components such as VoIP softswitches, gateways and media servers. The EdgeProtect Series products use a dynamic access control list to authenticate VoIP subscribers as they register with the hosted service. This authentication eliminates the need to manually program IP addresses of valid subscribers in other firewalls around the perimeter of the data center to enable scalability while reducing the workload of operations personnel.
- In October 2003, Edgewater Networks introduced a VoIP customer premise device that combines T1 CSU/DSU or E1 and an 8-port 10/100 Ethernet switch. The company said its new EdgeMarc 38T resolves NAT/Firewall traversal problems by providing a "voice-aware" firewall that supports SIP, MGCP, H.323 or SCCP to protect the enterprise LAN.
