[Sip-implementors] About received parameter in Via.

[Arnold Lee.]

Hi all   UAc is behind a NAT. Can UAc set special ip address in its Via "received" parameter ? This special ip address is not NAT source address and my private address. There is a special BOX for NAT and it is not outbound proxy and NAT.   According the 2543 bis, If it contains an IP address that differs form the packet source address, the server must add a "received" attribute to that Via header field. .............. if the top Via has a received parameter, send the response to the address in the "received" parameter.   After all, the server must send reponse message to received packet source address. I want to process the "received" parameter like follow.   1) If it contains an IP address that differs form the packet source address and there is no "received" parameter in top most via header, the "received" parameter contain the source address.   2) If it contains an IP address that differs form the packet source address and there is a "received" parameter in top most via header, the server is no action.   3) The server sends the response to the address in the "received" parameter.   What do you think about that ?   Best Regards Arnold   ------------------------------ Lee, Hee-suck (Arnold Lee) MIP Telecom, Inc Tel : +82-2-874-2300 H.P : +82-16-729-1496 E-mail : [EMAIL PROTECTED] ICQ Num : 62188694 MSN : [EMAIL PROTECTED] ------------------------------
