A cast iron sission joint would work.
And a Kaffer fitting, BUT I think we are talking legal here 
They do make a No hub couplimg for Extra Heavy Cast Iron as I use it all the time in the installation of cast Iron roof drains where a caulked joint is not practicable.
Most codes will allow an MJ (Mechanical Joint) much like a Vitriolic coupling.
