PRI to PRI

[SCs5thGen]

I am looking to tandem a TrixBox to a BCM over IP. Actually I will be using a PRI card in the BCM for incoming from the trixbox. It has been a long time since i have done anything like this. It will be a SIP initiated call from trixbox over IP to a box that converts from sip to PRI. Then that will need to go out the "real" PRI in the BCM. Do i just set up on the BCM the inbound route from trixbox as voip and have it look to the PRIs route out? I know how to do this from one BCM to another using all voip but it is confusing me throughing the "voiped" PRI in the mix.

Please help

Should use MCDN keycode and protocal is SL-1 plus remote package for access to pool from remote BCM. Build route as 9 absorb zero this will send the 9 and number for dialing out of the other BCM. Make the dialing plan DN for 9 11 digit and 91 -12 digits.

I will need a MCDN keycode even though the call from the trixbox will be coming in as a PRI? It is a voip call but I have a Patton, Sip to PRI, gateway that will convert it from sip to pri then into the BCM. If my thinking is right it will then be treated as DIDs using target lines for the ext to ext dialing. I am just confused on the tandem dialing, my route to build from the sip-pri to the existing outgoing/incoming PRI???
