It dint solve my problem. Am not able to get the proxy authenticate header values using the module you mentioned too. Does this allow to fetch the SIP header individually?

Thanks, Vivek

So I will be receiving the "407 Proxy Authentication Required" response from the third party server for the first INVITE.

I want to fetch the Proxy-Authenticate header present in the 407 response.

I browsed and tried using the pseudo-variables "$adu/$aa/$ar". It dint work.

I think you are looking for T_rpl: https://www.kamailio.org/wiki/cookbooks/4.4.x/pseudovariables#t_rpl_pv

So it might be something like $T_rpl($adu) or $T_rpl($hdr(Proxy-Authorization))

Yes, it use it to extract (part of) the contact header on a 302 redirect reply: $(T_rpl($ct){nameaddr.uri}) or some custom headers I inject in the redirector: $T_rpl($hdr(X-fax))

Maybe it worth saying that these variables can be used inside the failure_route.

If you need to get the header in [on]reply_route, then just use the $hdr(Proxy-Authenticate) and it will return the header body. Then look at transformations to extract parts of it.
