Fair enough. But it's important to understand that Kamailio is not a
piece of finished software like say, Asterisk or Freeswitch, where you
just edit some declarative configuration files and "enable the SBC
funcitonality" or whatever. It's more of a kind of SDK, almost, driven
by an imperative domain-specific scripting language, so you'd have to
meticulously script your desired outcomes. 

There are two different ways the term "SBC" is commonly used. One is
kind of folkloric in nature, and refers to a carrier and/or customer
endpoint-facing "traffic aggregation" element in a rather generic sense.
The other notion is somewhat more specific to the understanding fostered
by the commercial SBC industry, and includes some things Kamailio either
does not do well or to which it is not exceptionally well-suited. Which
one are you after?

Kamailio can certainly play the role you're wanting it to play, but you need
to be aware of the trade-offs. For instance, there are a number of
things that fall under the mainstream commercial understanding of SBC,
such as ASIC-assisted RTP relay, B2BUA-based topology hiding, various
types of registrar caching middlebox functionality, forwarding out of a
large number of network interfaces/VLANs, etc.
