Brad: Lucent 5ESS can treat a PRA (PRI) like a CCS7 or R2 route. This feature allow to route any number, including numbers outside the DID range. I know some class 5 switches (Lucent, Siemens, Ericsson, Nec, Alcatel and Italtel), and only Lucent 5ESS and Siemens EWSD provides this feature (at least in world-wide market, I mean, non US market). If you like to connect a VoIP gateway, in the 5ESS you can route any number, like local, national or international. I have * connected to our 5E switch, and it works good.
PRI was defined as the ISDN termination for customer side in 'high-speed' Nx64 or Nx56; supports all advanced features provided by ISDN and in general terms, provides full mapping for ISUP layer 4 data. At least for EuroISDN, for IN and AIN features, PRI only provides voice connection with SSP switch. PRI doesn't have a special messages replacing or adding features to INAP, because it haven't a message structure neither querys nor commands (you can't specify triggers in PRI signalling), only for ISDN termination related to call establishment.
