You don't say which version of Asterisk you're using, so I can't guarantee 
that the following will work for you, but I got this to work using Asterisk 
11.13.1:

In sip.conf, under the [general] stanza, define:
storesipcause=yes

You will get a warning to use hangupcause instead, but I haven't got that to 
do the same thing, so it's no substitute, I think.

Then, in your Dial() command, use M() to call a macro when the call gets 
answered.  https://www.voip-info.org/wiki/view/Asterisk+cmd+Dial

In the macro definition, you can use ${HASH(SIP_CAUSE,${CDR(channel)})} to get 
the SIP response code.  It returns values such as "SIP 200 OK".


Hope that helps,


Antony.
