<br>
<tt>The append_branch() itself is not doing any SIP signaling. It is only creating (internally, as data structure) a new branch for the request (to a new destination).</tt><br>
<br>
<tt>The signalling (to all created branches) is done by TM module when you relay the request out. The forking is a transaction level mechanism and it is handled by the TM module.</tt><br>
<br>
<tt>Best regards,</tt><br>

<p class="MsoNormal"><span style="color:blue">When append_branch() is called, it takes care of the forking process.

<p class="MsoNormal"><span style="color:blue">When we say it is used to fork the call, append_branch() takes care of sending the request out to that branch and as well maintaining the dialog and transaction information for that call leg or it is used only to
send SIP INVITE out? </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">Sounds like a basic question. But I want to make sure how it works.

<p class="MsoNormal"><span style="color:blue">Am assuming it takes care of dialog and transaction for that call leg and it maps the response to that call leg as well. Correct me if am wrong.
