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.
