Atis-- Keep me informed. I've been continuing the effort to improve the CDR accuracy. Give me specific test cases; and your using the SVN 1.4 branch head will help me, too, as I may have fixed bugs, and it's a shame to waste time on stuff I might already have fixed. I've spent weeks trying to upgrade CDRs to work right. I'm in the middle of an effort to make CDR's cover transfers (zap, and soon sip), and give folks enough data that they can successfully bill on any sort of strange transfer operation. I've found that if I rebuild CDR generation around bridging, and eliminate the code that posts CDR based on hangups, I can generate better CDR's in a transfer environment. No chunk of conversation can be lost this way. But the philosophy is a little different, and will give you headaches if you've already put in some work on billing. The main difficulty with this approach is that the transfer events aren't visible at a high level in the bridge, but happen within the drivers, so I have to some dancing between the drivers (sip, zap, etc), and the bridging code (res_features.c). Even if I leave the drivers out of it, just generating a CDR every time a bridge is formed and ended, allows me to make sure a CDR is generated if a conversation took place, something that right now, in transfer situations, is not happening. murf > > > On Fri, 2007-04-27 at 11:32 -0400, Scott Lykens wrote: > >> Hello all: > >> > >> I upgraded to 1.4.3 last night and use MySQL for CDR. > >> > >> I have noticed that 1.4.3 seems to log a lot of "crap" to CDR that > >> 1.4.2 did not.
