[SR-Users] question about dlg_var

[Julia Boudniatsky]

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.
