I'm running ccm 4.2(3)sr3 with CAR version 4.2(1.021.000), ART version 4.2(0.1). I have FAC configured and it works well, but when using CAR FAC/CMC report , only calls made from specific phones appears in the report. I made calls using diferent FAC from the same phone (whose calls dos not appear), but the situation is the same. This situation is independent of the phone model.
is CDR enabled on all the servers in the cluster?
if it's only enabled on one server then you will get CDR only for that particular server.
if this helps, please rate
