Pre-Sangoma DCAA Certification

I took an Asterisk Advanced class in 2014 and no longer have my certificate to show I obtained it during that time. Is there a way to reobtain that certificate at this time? I have retaken the dCAA exam on the Sangoma University site today and am awaiting grading (I don’t know if thats normal…?) but I need something to show a job offer that is doing a background check on me now.

The dCAA only lasts 2 years ?

How’d it go ?
