Sure! I've meet already with some guys here and had fun

Send me a PM anytime! I'm at Porto Alegre, so if going north tell with some time to get tickets

The issue is that PBX has nothing to do with that calculation, is StatServers job. PBX generates a CSTA event, then translated to TLib events, TServer generates and receives them, then StatServer gets a copy of these events and decides to analyze them or not based on the metrics defined on him.
Cleared is a diffent history, only works for VQs.
RONA is also another history, that was a distributed but not answered, then enters again, with DCID would be still 1 call Entered, without 2, but there for example, that 2 would disturbe customers stats...
Honestly I see no reason why not to use DCID, in all my years of metrics building and complex reports, never missed a single call or the explanation and control of it on metrics...Alcatel, Nortel, SIP Server, Cisco...never had the chance yet to work with Avaya, due the fact of being an Alcatel Partner keeps me away from it but still looking to work on it some day close. The only thing that changes always is the call flow or treatment some PBX does, for example, Nortel, used to do a Forward on agents extensions and "missing" calls were advertised, but then understanding the call flow and understanding the events generated was easy to make a match on Stats and deliver the customer a report were all numbers matched.
In resume, I think only a better analysis would be the best approach.
