<FONT SIZE="4"><FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:14.0px'><B>According to the way I interpret the attached compatibility matrix, the NM-HD-2V module with a VIC2-FXO card is compatible with the 3640 router. &nbsp;However, I haven&#8217;t yet been able to determine version of the IOS is required. &nbsp;I&#8217;ve uploaded a couple of different ones into the router but haven&#8217;t yet found one that will recognize the card. &nbsp;What am I not seeing here?<BR>
