[cisco-voip] Excluding extensions from CDR reporting

[Hames, Joel]

Thinking about this more, I do want VM information in my call accounting
reporting.  But I also want the option to filter these extensions out so
that I can get meaningful non-VM voice traffic reporting.  I will pursue
this more with the call accounting software provider.  Thanks for the
clarification, everyone.

if your using CER then 911 should not be an issue as it takes all the
911 calls and you don't really have a 911 or 9.911 route pattern.

 

on the other note.  Are you sure you don't want the VM data.  people
from outside still get VM if no one is there and there for I would see
this as needed info.

 

What are you doing with the reporting software that you don't what VM?

Thanks for the clarification and I apologize for the vagueness of the
example.  We are seeing both calls to our voicemail extension (2000) and

to the MWI extensions (2090 and 2091).  We recently disabled reporting
for zero duration calls, but your point is well taken regarding 911
hangups.  I'll check with our implementer to see if our Emergency
Responder installation will help offset this loss of detail.  As for the
voicemail extension itself (2000) that is logging all calls transferred
to VM, I'll work with RSI again to see what they can do to help filter 
out this information for reporting.

The verbiage provided is vague but i'm going to assume that CDR's for
MWI calls are the crux of the issue.  Those have been an issue before
and are certainly numerous enough to skew reporting.

The way CM is implemented Voicemail and the associated MWI transactions
are calls.  You can set CM service parameter "CDR log calls with zero
duration" to false so that CM does not record CDR for MWI.  However, you


risk losing CDR for other critical calls such as misdials/hangups to 911

where the caller hangs up before 911 service answers.  Most 911
districts consider these prank calls with a quota and begin charging. 

Otherwise, no, there is no way to filter these calls from CDR. The
system dumps out CDR's of all calls.  Parsing, filtering, and
correlating are the job of the "Call Accounting and Reporting" package. 

Just as Cisco generates the CDR flat files, RSI has to parse and import
every CDR flat file.  They have equal opportunity to filter these
requests.  As a bonus, RSI can do it without contending for
CPU/Memory/DiskIO that would otherwise be used for processing your 
actual calls.  It's a rather classic example of production vs.
reporting.
