As my research continues I see how badly phrased my question was.

A stateful SIP proxy and a B2BUA are very different beasts it would seem.

The former is best accomplished by taking Kamailio and using its
custom scripting language to write into to a database using one of its
DB plugins.

The latter can only be accomplished by using FreeSwitch, since the
above scripting language is rather limited.

My revised question is this: What API does does FreeSwitch expose to
implement a SIP B2BUA, and where?

In other words can you point me to any documentation for implementing
