SBO reduces bandwidth consumption using its proprietary encryption and compression technology. The Synchronous Bandwidth Optimizer reduces bandwidth consumption usage by 80% depending on the codec used. Surprisingly, SBO does this optimization without negatively impacting the voice quality.
Every VoIP call has generally two parts – voice data (payload, which is already compressed with codec) and protocol headers (i.e. SIP, RTP). The voice data part is already compressed with codec. If it is more compressed, it loses quality to significant extent. The overall performance also degrades. So, SBO does not meddle with the voice data; to ensure superior voice quality which is provided by the codec itself. SBO does not use SIP or RTP protocol, rather it uses its proprietary SBO protocol. The SBO protocol works with minimum overhead. This reduces bandwidth usage. The bandwidth used by SBO protocol is very low compared to SIP & RTP. SIP and RTP use a lot of bandwidth compared to the voice data they transfer. SBO does this without degrading the voice quality because it does not touch the media part / voice data at all. This is how SBO reduces bandwidth consumption.
Another way to reduce bandwidth consumption is by multiplexing. SBO protocol supports multiplexing. When number of call increases, bandwidth usage goes further down. This is vital for high scale termination businesses. In these ways SBO Solution reduces bandwidth consumption.
