What I saw was that, in the second Invite, the addpac sends the Invite with the the "to tag" that was attached by SER before (422 response). I belive that this is the reason of the 481 response from grandstream. I think it is a bug of Addpac. Is that correct?
Yes. It is correct.
A To-tag MUST NOT be attached by the UAC outside of a dialog and a dialog does not exist, because a failure response (422) does not create a dialog.
