Asterisk is a multiprotocol PBX, every error that arrives to the SIP  
channel is translated
(like all other signalling) then sent to the core. The core sends it  
out again on the other
channel that translates back to SIP. In this translation, which  
follows the details specs
for ISDN to SIP translation, some granularity is lost.
