don't be blended by marketing terms (like SBC is).

You can do SIP message inspection also with openser.

the big difference is:
- when buying a commercial SBC, you get a block box, which does lots of 
magic, runs usually fine, is impossible to debug, does not need lots of 
config and is quite expensive

- when doing it yourself you have to have some time for configuration 
and testing, get it for free, easy to debug, you can fix problems 
yourself. But you have to understand the protocol and openser to make a 
secure installation.
