Summary:                    In SIP to PSTN call, CDR disposition is ANSWERED
always
Description: 
I have installed a TDM 400 card in a system that has installed Asterisk
sucessfully.

I connected one PSTN line to TDM 400 card. Now, from a sip phone, i can
call any outside pstn landline or mobile number.

Problem is, from a sip phone when I dial a mobile/landline number and I
hangs up before other party answers the call, in CDR I got disposition as
ANSWERED, instead   of N0-ANSWER or BUSY.

Please let me know, Is there any way to get proper disposition.

This looks like a configuration issue (or, less likely, feature request),
which you should follow up in the support forum, or using IRC.  The key
phrase is "answer supervision".
