What is SBO Bandwidth Optimizer?

Hi, anyone here who has idea about SBO Bandwidth Optimizer? I am facing some quality issues with my system, therefore, a friend of mine, suggest me to use SBO Bandwidth Optimizer.
um new here and please pardon me if I make any wrong by making irrelevant post. Thank you,

Google it.

It is only for calls where you control both ends of the trunk. On Asterisk, you would use IAX to get a similar effect (there may be an option that you have to select).

Please note that this forum is not intended for questions. For that, you want Asterisk Support.
