<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>We're looking for informations regarding an INVITE
action we would like to plan for SER server;<BR>We're manufacturing a new SIP
phone, and in case of DSL-modem router, we're developing a special REGISTER with
2 Contacts for the same SIP phone: <BR>A public IP address, and a private IP
address. In each case, SER server is placed on external part.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Here is a scheme of what is
done:<BR>@IP1
<BR>SIP
phone1-----| <SPAN

</SPAN>@IPWan<BR> <SPAN
class=291500910-16102003> </SPAN>|---[modem-routeur]-----------(......INTERNET.......)-----------------[External

Location Table : SIP phone-1 <=> </FONT><A href="mailto:{@IP1"><FONT
face=Arial size=2>{@IP1</FONT></A><FONT face=Arial size=2> ; @IPWan}
<BR>@IP2 <SPAN

</SPAN>SIP phone-2 <=> </FONT><A href="mailto:{@IP2"><FONT face=Arial
size=2>{@IP2</FONT></A><FONT face=Arial size=2> ; @IPWan}</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>What we want to do is following: <BR>When SIP
phone1 is looking for a call-session with SIP phone2, we want SER server to
compare WAN contacts in mysql location table, and in case of same Response (<A
href="mailto:=@IPWan">=@IPWan</A>),<BR>it will redirect INVITE by sending a "302
Moved Temporarly" to SIP-phone1, with a special new contact as SIP-phone2
private IP address (@IP2).<BR>Could anyone ever done that before?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Any ideas are welcome.<BR>Really thanks for your
support.<BR>Best Regards.<BR>Marc</FONT></DIV></BODY></HTML>
