Looks like the FacilityIE invokes an operation called 'McidRequest'.  
Q.951.7 contains most of the juicy details.  Perhaps your carrier may  
recognize some of the verbiage here.

I got MCID setup on my CallManager and phones, but after speaking  
with my PRI carrier, they said that they don't have a feature related  
to malicious caller identification (MCID).  I've got H323 gateways  
and PRI lines from ATT (formerly SBC).  At this point, the MCID  
feature is not doing me any good if I can't work with the PRI carrier  
to identify a malicious caller.  Does anyone have MCID working with  
their local PRI carrier?  Am I missing something that I should ask my  
PRI carrier for?

Thanks in advance.
