Volga,
I must be misunderstanding. If you are able to determine the correct
receiving interface in OpenSIPS and you are using the Path header to
communicate that to the next hop destination, I'm not sure I'm clear
on what the issue is you are still trying to solve?

Hello Ben,
Yes, I create logic like this
if(!has_totag() && is_method("INVITE")) {
create_dialog();
if($Ri== vip1 ip addr) {
set_dlg_sharing_tag("vip1");
$avp(vip) = "vip1 ip addr";
} else if($Ri== vip2 ip addr) {
set_dlg_sharing_tag("vip2");
$avp(vip) = "vip2 ip addr";
} else if($Ri == vip3 ip addr) {
set_dlg_sharing_tag("vip3");
$avp(vip) = "vip3 ip addr";
}
}
not sure if this correct approach. In theory $avp(vip) can be
used for
rtpengine or other operation require correct ip in body, but
issue that
call flow, because INVITE come from external interface first then
it
forwarded to LAN via dipatcher.
