[asterisk-users] CDR shows NO ANSWER when call is really ANSWERED

[voiplist]

Tonight I made 3 calls, all which were answered at the remote end. All
three calls showed up in the CDR but only one showed a disposition of
"ANSWERED" the other 2 had a disposition of "NO ANSWER".

Few other things to note, on the calls with no answer the bill seconds
is of course 0. After further testing we noticed that only calls to
this one particular number over 16 seconds will show up as ANSWERED
calls under 16 seconds show as NO ANSWER.

On the calls which show ANSWERED, the bill seconds is always 16
seconds less than the duration.

There seems to be some bug that was submitted about this but I don't
see any further info. Not sure if this is really a bug and if it was
resolved, which version, was there a patch etc.

The bug is here:

These calls are not getting billed and we are paying our carrier for
them so this is a problem to say the least.

Thanks for any help you (the list) can provide.
