Hello,

 

I am using two different on_reply routes:

 

if (is_method("INVITE") && !has_totag()) {
.......
       t_on_reply(REPLY_TO_SOURCE);
}

route[WITHINDLG] {

if(has_to_tag()) {
........
      t_on_reply(REPLY_IN_DIALOG);
}

May be it will help.

 

Best regards,

Julia.

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?
