<p class=MsoNormal>There are two major issues related to the implementing of
such feature:<o:p></o:p></p>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>1. You expose your server to information provisioned in a
remote system<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>2. OpenSIPS child may block waiting for the response from
the remote XCAP server<o:p></o:p></p>

<div>
<div>
<div>
<p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";
color:black'>So though this feature is well defined in the standards, it can
introduce a lot of problems for the operator that implements it. <o:p></o:p></span></p>
