<p class="MsoNormal">Hi Richard, </p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I really appreciate your help!</p>
<p class="MsoNormal">However, the initial problem is to avoid the forking for the scenario you mentioned (no matter if it is serial or parallel) if the INVITE is coming from the GW with Request-Disposition: no-fork. The issue is with the “to tag” parameter:</p>

<p class="MsoNormal"></p>
<p class="MsoNormal">Here is my original question, I hope you have some idea for this.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> I have call forwarding busy/no answer scenario: A number is from a</p>
<p class="MsoNormal">> gateway, B and C numbers are our own subs.</p>
<p class="MsoNormal">><o:p> </o:p></p>
<p class="MsoNormal">> The gateway is sending us the INVITE message with</p>
<p class="MsoNormal">> “Request-Disposition: no-fork” header field.</p>
<p class="MsoNormal">><o:p> </o:p></p>
<p class="MsoNormal">> That means we must use one dialog for the mentioned scenario.</p>
<p class="MsoNormal">><o:p> </o:p></p>
<p class="MsoNormal">> Currently the To tag we are sending to the GW in the first 180</p>
<p class="MsoNormal">> ringing/181 Call is being forwarded messages are different to the</p>
<p class="MsoNormal">> To tag in the second 180 ringing and 200 OK (SDP).</p>
