Hi,

 

Proxy will forward the response based on Via header.

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
