<p class="MsoPlainText">As VG310 supports T.38 fax relay, and modem pass-through and your call flow says:
<o:p></o:p></p>
<p class="MsoPlainText">- VG310 as SCCP, then you will be limited to use T.38 fax relay methods. As Protocol-based switchover is not supported with SCCP.<o:p></o:p></p>
<p class="MsoPlainText">- And provider not supporting any fax relay methods, then you will need to do the below:
<o:p></o:p></p>
