I would think that anything above 200 sessions is pretty significant and I would lobby for a dedicated device. You can see that this question is address here, but with no specifics:</div><div><br></div><div><a href="https://supportforums.cisco.com/document/69976/frequently-asked-questions-cisco-unified-border-element-cube#Q11:_Does_CUBE_have_to_be_run_on_a_dedicated_devicerouter">https://supportforums.cisco.com/document/69976/frequently-asked-questions-cisco-unified-border-element-cube#Q11:_Does_CUBE_have_to_be_run_on_a_dedicated_devicerouter</a><br></div><div><br><div class="gmail_quote">On Wed, Mar 25, 2015 at 8:09 PM Barry Howser <<a href="mailto:bhowser5050@gmail.com" target="_blank">bhowser5050@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div><div><div><div>Thanks, that helps!<br><br></div>So when it comes to calculating number of SIP sessions that can be supported ... lets use your example of100 sessions;<br><br>1.)
