Hi,
Proxy will forward the response based on Via header.

Subject: [SIPForum-discussion] Query related to Basic SIP call
Hi All,
As per RFC 3261,
Via, To, From, C-seq, Call-id, Max-Forwards are the only mandatory
headers in an Invite request
But we still add Contact Header to know the actual address of UAC
Suppose, in an Invite request there is no contact header,
so when Proxy receives 180 ringing response, how it will forward that
response to UAC who initiated the Invite.
Thanks in advance
Regards
Gaurav
