Is wireless TTL possible with the Sigma SD15?

I have a Sigma SD15 DSLR and a Sigma EF 610 DG Super flash. Both allegedly support wireless TTL, but I cannot find triggers or even a recommendation for triggers that will enable it. I’ve also read about problems with off camera TTL for some Sigma models. Is wireless TTL even possible/practical with this camera? Thanks.
