<h3><a name="Asterisk10Application_SIPRemoveHeader-Synopsis"></a>Synopsis</h3>
<p>Remove SIP headers previously added with SIPAddHeader</p>
<h3><a name="Asterisk10Application_SIPRemoveHeader-Description"></a>Description</h3>
<p>SIPRemoveHeader() allows you to remove headers which were previously added with SIPAddHeader(). If no parameter is supplied, all previously added headers will be removed. If a parameter is supplied, only the matching headers will be removed. </p>
<p>For example you have added these 2 headers: </p>
<p>SIPAddHeader(P-Asserted-Identity: sip:foo@bar); </p>
<p>SIPAddHeader(P-Preferred-Identity: sip:bar@foo); </p>
<p>// remove all headers </p>
<p>SIPRemoveHeader(); </p>
<p>// remove all P- headers </p>
<p>SIPRemoveHeader(P-); </p>
<p>// remove only the PAI header (note the : at the end) </p>
<p>SIPRemoveHeader(P-Asserted-Identity<img class="emoticon" src="/wiki/images/icons/emoticons/smile.gif" height="20" width="20" align="absmiddle" alt="" border="0"/>; </p>
<p>Always returns <tt>0</tt>.</p>
