Session Border Controller

The ALLO Session Border Controller(SBC) is the industry's first open source software-based SBC that delivers the scalability with the advanced features and functionality compromise. The SBC features media transcoding, security technology and policy based routing.

A Session border controller(SBC) is used to control VoIP signaling and media streams. SBC is responsible for setting up, conducting, and tearing down calls.

SBC allows owners to control the types of call that can be placed through the networks and also overcome some of the problems caused by firewalls and NAT for VoIP calls. A common location for a stand-alone SBC is a connection point, called a border, between a private local area network (LAN) and the Internet. SBC polices real-time voice traffic between IP network borders ensuring your private network is robustly secure and fully manageable.
