Outbound E1/PRI RDNIS question

–Incoming SIP–> Asterisk ----- ----> MGW/PSTN —forwarded -->

If a Sip voice call is received via Asterisk and redirected back out to the E1/PRI
Can ISUP information grabbed for call tear down to identify whether the call has been call forwarded?

I understand inbound E1/PRI, we can grab the RDNIS to find out if the call is a redirected call but my scenario is the opposite.
