Mitel SX-200 trunking to *?

I have a Mitel SX-200 (not the SX-200 ICP) and not having much luck finding technical docs/info I’m lookin for…

Just wondering if anyone has experience integrating this platform with *, what I’d like to do is trunk from the SX-200 to a * server with IAX/SIP clients attached to it. The SX-200 has a couple PRI coming into it, which we’d need to keep for the incoming POTS lines.

Any help or pointers to real documentation would be great, thanks all!
