Fixed it.

It was a combination of me using the wrong function name in PrepSDKCall_SetFromConf, using SDKConf_Virtual instead of SDKConf_Signature and editing the sp file but not recompiling and reloading it onto the server. At one point I was checking if I even screwed up the encoding of the file (UTF-8 w/o BOM).

Please award me the dumbass and moron of 2016 award.

Thanks for all the help!
