It gets a little murky with the flex DSPs and how many are required depend on what voice codecs are being used.<div><br class="webkit-block-placeholder"></div><div>Your best bet is to configure a sccp profile for either conference or transcode. See what the 'max-sessions' command will allow you to set. If you have enough free DSPs then when you do 'max-sess ?' the result will include a non-zero number, ie '0-10' or similar instead of '0-0'.</div><div><br class="webkit-block-placeholder"></div><div>Yes you do need to add a CFB in CM with a name that matches whatever you set in the 'register' command under the sccp profile on the router.</div><div><br><div> <p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">-Ryan</font></p> </div><br><div><div>On Jan 25, 2008, at 3:20 PM, Lelio Fulgenzi wrote:</div><br class="Apple-interchange-newline"> <div><font face="Arial" size="2">I've got a 3845 with a PVDM2-64 as far as I can tell.
