[Freeswitch-users] Proto specific hangup cause issue

Tue Dec 9 08:12:01 PST 2008

Hello,
This is just my 2 cents ... but my experience has been that trying to catch
all of the various variables (i.e. from XML_CDR) or otherwise can be a
little trying (a row in your CDR database could be over 100 fields long!).

The best option here is to catch the UUID's for the 2 call legs, capture all
SIP messaging, parse and dump the messaging, and then correlate the calls
from the CDR from there.

Much easier than trying to do it from FS ... and most folks want to see SIP
captures anyway (very broad set of tools to debug).

Measuring things like ASR, PDD, etc in my opinion is much easier from the
raw messaging than trying to do something with FS CDR records.
