Introduction to Session Border Controller (SBC)Added by Papergrl
Description:
A Session Border Controller (SBC) is a device used in some VoIP networks. SBCs are put into the signalling path between calling and called party. The SBC acts as if it was the called VoIP phone and places a second call to the called party. The effect of this behaviour is that not only the signaling traffic, but also the media traffic (voice, video etc) crosses the SBC. Without an SBC, the media traffic travels directly between the VoIP phones.
