Hey guys, I'm running FR1.0.5 with unixODBC (Sybase) backend and I'm trying to bill calls generated from Sip Express Router (SER). The problem that I have is the following scenario: When UserA calls UserB: SER generates a star-record where the Calling-Station-Id is UserA and the Called-Station-Id is UserB, this is the desired and always the correct behavior. When UserA hangs up on UserB: SER generates a stop-record where the Calling-Station-Id is UserA and the Called-Station-Id is UserB, this is the desired and correct behavior. But if UserB hangs up on UserA: SER generates a stop-record where the Calling-Station-Id is UserB and the Called-Station-Id is UserA, this is the undesired and incorrect behavior. To me the Calling-Station-Id and the Called-Station-Id should be the same for both start and stop records, am I right by thinking that? According to the developers of SER/OpenSER, this is the correct behavior, whoever sends the hangup signal (BYE or CANCEL) is considered the Calling-Station-Id, and they are unwilling to modify or create a patch to "fix" this. So for my purposes, i need the Calling-Station-Id and the Called-Station-Id to be the same on both the star and stop records, since the start record is always correct, what do I need to do to have FR "fix" the stop record when it receives it to show the same Calling-Station-Id and the Called-Station-Id as the Start Record? Thanks in advance, Lenir
