But for a lot of cases they're not modifying To/From for that reason - they're modifying it to either "fix" them for specific interop reasons, or to hide topology (ie, when it contains IP Addresses or hostnames). Those are the cases I'm trying to get the information through.
DY> Just to add to what Hadriel said, one of the additional arguments *for* an SBC that I've had given to me by different vendors at various shows is that they can "normalize" SIP and make SIP interoperability actually work between different vendors. The SBC understands how exactly Vendor X speaks SIP and how exactly Vendor Y speaks SIP and can then enable the interconnection/interoperability. So the reality is that there are SBCs out there that view as part of their function to "fix" SIP so that it can be interoperable. In doing this "fixing", one can expect that the SBCs would be changing headers.
