[SR-Users] First Invite

[Duarte Rocha]

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
