<div><p>Hi all!<br />I use opensips 2.1 with uac module. One of my carriers wants to authenticate not only INVITE, but also BYE request. In this case i have to increase CSeq of second BYE (with authentication header), but opensips don't increase CSeq itself, so i should increase it manually in failure_route after call uac_auth function. For INVITE authentication process, opensips increase CSeq automatically, so question is can opensips increase CSeq of some authenticating requests besides INVITE (eg UPDATE, BYE) and if it could be done, how to do it?</p></div>
