To help more with CDRs.
The built-in module with FreePBX (CDR reports) is good for most. I like it, and it works well, but for some it is lacking.
In a few of the commerical systems: they do not have anything CDR (this has been a drag): sort of the reason a few people “put FreePBX in front” of these systems, so they can have a CDR report (even emailed to them).
Check out the free version of Asternic’s CDR reports
(not to be confused with their) Call Center Stats program
Check it out here:
About | Asternic Call Center Stats
They also have a $100 (onetime) paid version for this program
You can run BOTH the FreePBX CDR Reports module and Asternic CDR Reports on the same system because they have a different view of the call database.
Keep going!
