asterisk users - Nov 2008 - Use of optional new number in ISDN release 22

Hello,

	Has anyone got any ideea if I can use in Asterisk the "new called party 
number optionally included in the diagnostic field" for release cause 22 
in ISDN?
	A callcenter gets lots of this messages from the telco and it would be 
nice if I could tell them that the number has changed, and that the 
number is xxxxx....

Thanks,
