908e SIP to PRI mask RURI with To header on inbound to SIP before PRI handoff

[sipjunky]

Working with a 908e with SIP trunks on the WAN side and PRI handoff on the back side.  When a number is forwarded to our 908e on the SIP side from the outside, the RURI is not a number on the PRI side of the PBX.  We need to be able to replace the RURI with the To: header information before sending to the PBX via the PRI.  The only way we can see to do it in this configuration is using HMR on the inbound.  Does anyone know how to do that method or have an easier method to handle this issue?

under the "voice trunk type sip" seems to do what I need to make this work.
