<p>The same (similar) result should be when not using topos, because the other side didn't give any contact where to forward the BYE.</p>
<p>So in this case you have to route the BYE like you did the INVITE. Eventually store in an htable where you sent the INVITE (using call-id as a key) and forward the BYE there. Something like: if the ruri of BYE is myself and there is an item in htable, then route the BYE there.</p>
<p>I am going to close this issue, the behavior is like expected without topos. If there is more that you want to discuss about routing a BYE when no Contact was provided (with or without topos), the best is to use sr-users mailing list.</p>
