<P> </P>
<P>I am playing around the idea of setting up an asterisk box on the public domain.</P>
<P>This box will then be connected to various other sip providers for LCR for low cost calls.</P>
<P>It was recommened that I use a SBC. I never used SBC. From what I understand</P>
<P>it can help with different aspect when it comes to SIP communication such as security</P>
<P>and billing.</P>
<P> </P>
<P>Is SBC really necessary? If so what would be the ideal configuration?</P>
<P> </P>
<P>thanks</P>
