The logic for T.38 negotiation lives all in the res_pjsip_t38 module and
the request to negotiate works using a control frame which is handled by
the t38_interpret_parameters function. It's up to that to initialize
things and then request that a session refresh occurs (which sends the
re-invite). That'd be the place to look.
