The 407 Clerk may have a process to show proof of compliance and effectively dismiss the ticket - the Miami-Dade Clerrk does (if none of my 407 colleagues chimein about this then you should call them and ask).
If not then you enjoy the same 3 options that anyone cited in Florida for a non-mandatory court appearance traffic citation enjoys: A) Pay it (in which case you will get points assessed on your driver license); B) Elect driving school (in which case points will NOT be assessed, but you can only do this 5 times in your life and cannot do it 2 times within any 12 month period); or C) Set it for Court and challenge it. In all 3 events you face fines and court costs on top of what I have outlined, and, regardless of which you choose, in all 3 cases you must make an election within 30 days of issuance of the citation.
That said, in my opinion, the best defense for any traffic citation anywhere is to hire a local traffic ticket lawyer. I can't speak to the 407 per se but in Miami, Fl, where I have been a practicing criminal defense lawyer for nearly a quarter of a century, there are many skilled and experienced traffic lawyers who know the law, the procedure, the Judge and probably the cop. In short you will almost certainly get both competent representation and a better result for a relatively small fee / investment.
I hope that I have been helpful in answering your question.
