You're definitely right, but they must be in the same Dialog, but my case it doesn't recognize it as it is in any current dialog. </div>

<br>
End-to-end ACKs (to confirm 2xx reply to INVITE transaction) and BYEs<br>
are all separate transactions in their own right; they share a common<br>

you expect them to match a known transaction?<br>
