[asterisk-users] 0 duration but non-zero billsec in mysql cdr

[Jaswinder Singh]

 I was just going through my call records ( stored in mysql database
by cdr_MYSQL module ) and saw a record having duration = 0 and billsec
of more than 50 seconds . I did a query on cdr where duration <
billsec and saw that there were infact some 250 records with duration
less than billsecond ( table had around 4,00,000 records) . Did anyone
came across this ?
I also checked csv files and they had same record with duration 0 and
higher bill seconds .

Happen with both asterisk 1.2.17 as well as 1.2.18
All sip to iax/sip calls  . Destination numbers were valid.
Dialplan maintained with freepbx .
