Session Border Controller
Prevantage Fusion's Session Border Controller (SBC) provides control over the signaling and media streams needed in setting up, connecting and disconnecting any VoIP calls. SBCs allow you to control the calls that can be placed through the networks on which you reside, and also overcome some of the problems that firewalls and NAT cause for VoIP calls.
As a Public VoIP service provider, you would use SBCs to allow the use of VoIP protocols from the private networks of your users with Internet connections using NAT, and also to implement security measures to ensure a high quality of service.
