<p>As I said, the BYE in early phase is ok, when willing to end a specific branch, but typically after 183 which establishes a connected brach for early media. Maybe the BYE was sent in this case because of the Contact in 180, thinking that was an established branch. That was the reason I decided to skip adding the Contact in the response sent out if the incoming one does not have one.</p>
<p>Maybe you have the chance to test and see if the BYE is still sent when no Contact is in 180.</p>
