Greetings, How can i identify the first Invite received by Kamailio in a dialog. I'm checking for the To-Tag in order to identify the first one. However, if the UA retries the same INVITE (because of a timeout for example), it won't have To Tag and it won't be the first INVITE that i'm receiving in that dialog. Is there any flag or variable that i can use to identify the first Invite received? Thanks in advance _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
