To be clear: you want to see a Call Detail Record immediately after someone has dialed an emergency number, such as "911". You do not want the system to wait until the caller has completed the call. Correct?
If so: I have worked with CDR for many years, and consider myself to be "proficient" - but I do not know if what you need is possible. There are eleven AMOs that MUST be involved, and many more AMOs that MAY be involved with CDR, all of which provide so many parameters and options - which is why I consider CDR to be THE most difficult HiPath 4000 "app" to master. By default the active Switching Unit compiles the pertinent raw data AFTER the call has completed, then hands that data to the ADP for proper processing & handling. My first impulse is to respond that the system was not designed to produce a CDR record immediately after a certain number is dialed (BEFORE THE CALL COMPLETES); however CDR is one of those "never say never" apps, so I will take a deep look this week if possible.
Is the goal to absolutely use CDR, or would you be interested in alternative methods to signal the occurrence of an emergency call?
