It's not; I know that the originating site is sending it, but it never 
seems to get delivered:

Dec 19 04:35:02.285: ISDN Se0/1/0:15 Q931: RX <- SETUP pd = 8  callref = 
0x001D
         Sending Complete
         Bearer Capability i = 0x8090A3
                 Standard = CCITT
                 Transfer Capability = Speech
                 Transfer Mode = Circuit
                 Transfer Rate = 64 kbit/s
         Channel ID i = 0xA1838A
                 Preferred, Channel 10
         Progress Ind i = 0x8583 - Origination address is non-ISDN
         Calling Party Number i = 0x00A3, N/A
                 Plan:Unknown, Type:Unknown
         Called Party Number i = 0xC1, '92400100'
                 Plan:ISDN, Type:Subscriber(local)

         Channel ID i = 0xA9838A
                 Exclusive, Channel 10

callref = 0x001D
         Cause i = 0x8790 - Normal call clearing

callref = 0x001D

That's what I figured.
