Yep CMR calling from on-prem endpoint is little more than a B2B call. You’ll want to follow the WebEx guide though, and setup the dedicated DNS zone as it does deviate from the standard DNS zone a little.

<div>As long as the <a href="mailto:xxx@site.webex.com">xxx@site.webex.com</a> URI (whether it’s a PMR or actual meeting room) is not transformed by the Expressway, the call should be free (i.e. does not consume an RMS license).</div>

<div>We’re finally taking a turn (not to be confused with TURN - hahaha) at getting CUCM talking to WebEx. Im guessing this is simply a B2B setup with the need for licenses. </div>
<div><br>
</div>
<div>The question I have is whether or not I should be activating ACLs anywhere along the path to avoid the expressways from getting hammered and clogging up the logs. </div>
<div><br>
</div>
<div>We’ll be enabling this on the MRA expressway pairs for the time being. </div>
<div><br>
</div>
<div>From my understanding, MRA uses 5061, 8443, 5222 inbound and B2B uses 5060. </div>
<div><br>
</div>
<div>Would it be advisable, to build ACLs only allowing certain address (space) to connect?</div>
<div><br>
</div>
<div>This would be on top of any rules/zones we build into the ExpE and CUCM (css). </div>
<div><br>
</div>
<div>We’re trying to avoid the obvious impact of scanning Ip addresses/uri’s for sip connectivity. </div>
<div><br>
</div>
<div>What are people doing?</div>
