Hi,
If I understood correctly the original question was to identify, in a reply
route, a 200 OK coming for an initial INVITE.
In the reply route the 200 OK will always have a to tag (unless the UAS is
broken), so you cannot this condition.
Regards,
Federico

Hi,
Sorry, but why not to check has_totag again? Why we need a flag?

Hi,
$dlg_var is not available at this stage of the dialog:
http://www.kamailio.org/docs/modules/devel/modules/dialog.html#idp19330392
To achieve your goal you can use there an avp or a flag, which are bound
to transactions.
Something like:
#define INIT_FLAG
if (is_method("INVITE") && !has_totag()) {
$avp(is_init_invite) = 1;
# or
# setflag(INIT_FLAG);
}
onreply_route {
if (is_method("INVITE") && t_check_status("200")
&&
$avp(is_init_invite) == "1") {
# or
# if (is_method("INVITE") && t_check_status("200")
&&
isflagset(INIT_FLAG))
#
# do somting
}
}
Regards,
Federico

I want to distingguish 200 OK is for INVITE or reINVITE。
so I do this:
request_route {
if (is_method("INVITE") && !has_totag()) {
$dlg_var(is_init_invite) = "1";
}
}
onreply_route {
xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]");
if (is_method("INVITE") && t_check_status("200")
&&
$dlg_var(is_init_invite) == "1") {
# do somting
$dlg_var(is_init_invite) = "0";
}
xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]");
}
What I confuse is：
When I recive 100 Trying LOG is
[100 - Trying][is_init_invite:0]
[100 - Trying][is_init_invite:1]
why is_init_invite is 0?
