[OpenSIPS-Users] OpenSIPS as SBC

[Răzvan Crainea]

Note that when I'm talking about a proxy, I am not saying blindly 
passing messages. You will still be able to normalize traffic, impose 
security, or use any OpenSIPS module that does the specifics of your 
requirements. My point is that you don't need B2B capabilities for an 
SBC, as this will complicate your work exponentially.

Best regards,
Răzvan
