 Every outgoing call regardless of whether or not it is answered or

 As a test I intentionally rang numbers that would be busy or

 might be going wrong?

Are you using analogue lines? Such lines are considered answered as
soon as the number has been dialled by the Zaptel interface.

Yes they are analogue lines.

I am sorry I did not see anything in any of the docs about analogue
lines causing ANSWERED response on all calls.

Could you point me in the right direction to a fix or setup that fixes
this situation?

The only real fix is to get some form of digital service, either ISDN
or VoIP. There is no reliable means to detect when a call has been
answered on an analogue line, so Asterisk doesn't bother trying.

The usual kludge for analogue PBXes is to assume that a call was
answered only if the recorded time is longer than a certain number of
seconds.

Hhmm well that's annoying

Is the kludge done at the software side when the data is pulled out for
accounting and being under say 45 seconds is a no answer or busy? Or is
there a tweak that can be done at the database itself?

So by that any calls that go out over the net using IAX to the telco are
considered digital and will report correctly?

Since you're using PostgreSQL, you can use a trigger to mangle the
data before it hits the database. In fact, there's no reason why you
couldn't log to a view rather than a table (but again, you will need a
trigger for the actual INSERT.)

For MySQL and other glorified flat-file databases, you would need to
postprocess the data. You may feel more confident skipping triggers
and doing this anyway.

 are considered digital and will report correctly?

Yes. You will probably be able to make the simple assumption that if
dstchannel ILIKE 'Zap/%' , you're going to have to fudge it, otherwise
it's correctly recorded.

Thank you for your help sir it was very informative I am going to write
the trigger with my own rules for the database and see how I go :-)
