Yeah, my bad. It is the source address as seen by the UAS. This i

When the server transport receives a request over any transport, it MUST examine the value of the "sent-by" parameter in the top Via header field value.  If the host portion of the "sent-by" parameter contains a domain name, or if it contains an IP address that differs from the packet source address, the server MUST add a "received" parameter to that Via header field value.  This parameter MUST contain the source address from which the packet was received. 

This is to assist the server transport layer in sending the response, since it must be sent to the source IP address from which the request came.

Please refer RFC 3581.

"The source IP address is conveyed in the "received" parameter
in the topmost Via header field value of the response."

It adds the local address of the local interface on which the INVITE was received.

I have a doubt regarding "received" param.

How a proxy forwarding a SIP message adds "received" param in Via header ?


Does it(proxy) adds its own address or address from where it received the packet ?


Thanks,
Sandy
