Matthew,

Look for the mediaproxy module.

That said, do be aware that a proxy is, by definition, not like an SBC. 
  SBCs have many other capabilities a proxy does not;  a proxy is a 
relatively "thin" interoperation layer.

Perhaps the recently introduced b2bua module is brought to bear on that 
somewhat, but classically, OpenSIPS is a proxy.
