      <br>
      The RFC3261 says that any requests with reply (so no ACK) can/may
      be subject to authentication. So SIP-wise, it is fine. In the
      real-life it is quite unusual, still not SF :).<br>
      <br>
      Regards,<br>

        <div>Hi list,</div>
        <div> </div>
        <div>is it normal at all — to authenticate BYE requests?</div>
        <div> </div>
        <div>I’ve checked RFC 3261 now, but haven’t found anything
          corresponding to this.</div>
        <div>Neither if it’s normal, nor if it’s not normal.</div>
