Is there a doc available that would show me how to configure a 908e for a SIP to SIP trunk?

I'm looking to use an Adtran 908e in a SIP - SIP trunk configuration for Enterprise customers who want to connect voice services from our switch to an IP PBX. We've configured SIP to PRI but I'm looking for a pure SIP configuration guide if there is one out there.

Thanks!
