A session border controller (SBC) server helps to secure a converged network by:
ensuring that CTI applications on the enterprise network are only able to control registered and authorized voice terminals.
terminating all SIP sessions initiated outside of the enterprise at the edge of the enterprise network
recording all voice calls taking place between voice endpoints on the enterprise network and those outside the enterprise network
eliminating the need for expensive firewalls on VoIP servers, desktop computers running softphones, and individual voice endpoints.
Deploying network address translation (NAT) in a converged network eliminates the need:
for dynamic host configuration protocol (DHCP) servers to assign addresses to voice endpoints.
for firewalls on servers, desktops, and voice endpoints.
to use STUN to establish sessions between local and remote voice endpoints.
to assign public addresses to voice endpoints.
