[asterisk-users] Need help understanding CDR

[RSCL Mumbai]

Hi,

Attached is a sample CDR.

I need some help to understand the "billsec" column.
PS: the time value in billsec & duration is same.

With reference to the attached log, what does the 10 sec / 6 sec / 2
sec correspond
to:

(a) Time between call connection to asterisk and disconnection from
asterisk?
(b) Time after welcome greeting and before hangup -- the time the call rang
on the extension?
(c) Or any other scenario

Thank you in advance.

Best regards,
Sans
