Features
Direct Connection Between VoIP Networks
As an inter-domain portal, the Call Relay SP switch provides direct IP connection between multiple networks.
The switch eliminates the need to link two or more VoIP networks via PSTN gateways. See Figure 1-2.
A direct connection between VoIP networks provides lower latency and the best possible voice quality by
eliminating multiple compression/decompression steps when linking multiple VoIP networks.

NATAccess™
NATAccess is an intelligent network address translation technology. It enables VoIP networks with multiple
H.323 endpoints to operate behind firewalls equipped with Network Access Translation (NAT); this provides
maximum network security. NATAccess simplifies deployment and installation by eliminating the need to
place the Call Relay SP on a public IP network. Using NATAccess provides an easy, secure, expansion
between multiple VoIP sites.
