[asterisk-users] 'NO ANSWER' with cdr duration of 0

[Josh McAllister]

I have a system running Asterisk 1.6.2.6 that generates about 80k
calls/day. Calls are fired from Asterisk Manager (async originate -- 60
second timeout). I am capturing 100% of the originate responses
(recorded in DB). About 5% of the calls result in a reason code of '3'
(Remote End is Ringing). CDR Disposition of these calls is 'NO ANSWER',
and billsec is 0. All good there. What's confusing me is that in *all*
these cases duration is also recorded as 0. IIRC, duration should be
time spent in the system, so should be roughly equal to my timeout (60
sec). Is this a bug, or am I not understanding correctly? 

I know there was a bug where all calls were recorded as 'NO ANSWER', I
was plagued with that until updating to 1.6.2.6, this does not seem to
be related. 

Any feedback is appreciated.

Thanks,
Josh McAllister
