Never seen such a thing: I have two systems, an sv8500 and a 2400ICS. They are CCIS connected to each other. SMDR recording PC is connected to the 8500 via rs232. SMDR records for calls made on the 2400 are sent to the 8500 via the ccis which in turn, sends them to the PC. This is Centralized Billing... This has been working for over a year without a hitch.
Yesterday afternoon however, I noticed that my SMDR pc only shows calls made on the 8500, but nothing coming from the 2400. Just out of the blue it stopped. Checking the last calls reported by the 2400, and what programming changes were done, revealed nothing useful. The last programming change I made was 2 hours before the problem started, and these changes were made on the 8500, using AFRS and AOPR command (to change the routing of calls starting with certain digits). So, I'm totally baffled. Also, went through the manual to check the programming steps for Centralized Billing and SMDR, but again, found nothing wrong. CCIS link works fine for voice calls, and can't really monitor what goes on on the data channel.
Then, I set up the 2400 to report SMDR on its own serial port instead of the CCIS, and when I connected my PC, it dumped about 10,000 records from its buffer. But, while call records always start with KA for outgoing calls, KE for incoming calls and KB for station-to-station calls, I saw a bunch of records starting with KH?!?!? What is that??? Also, those records seem incomplete. Won't show authorization codes used to make the call.
I know that to debug this, best would be for anybody to be on-site, and this information may be way insufficient to advice on handling, but at this point I take any suggestions as I'm loosing smdr records big time and in an enterprise environment, that really bad.
Thanks
