Diversion information from ISDN?


#1

Is this possible at all to get Diversion information from the call coming from ISDN over ZAP/DAHDI?

Here is the log from a diverted ISDN call:

Caller 526691185 dialed 0506580680 and was diverted to 722162230.

According to any RFCs, does PRI send along any diversion information?
