<p>Hello,</p>
<p>well, the specs say that all 200ok must be forwarded to the
caller, because a middle point cannot decide for the user making
the call. Even sending an ACK for the 200ok from a middle point is
not enough because the callee of that branch will think it is in
an active call.<br>
</p>
<p>The caller can take different actions, the usual is to ACK the
2nd 200ok and then immediately send BYE. But it can also decide to
end previous branch and switch to this one (e.g., uses better
codecs, or has video, etc...).</p>
<p>Cheers,<br>
Daniel<br>
