</div>
<div>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt; font-family:"Calibri","sans-serif"">In CUCM we have the Right-FAX server utilizing h.323, this all works great for External parties to fax in and for Right Fax to send out.</span></p>

reason is because Cisco’s SCCP does not support t.38</span></p>
