Another difference is that the SDP offer can now present multiple codecs. We installed a lab with a pool of one Server, and a different machine for the Mediation Server (All of them Virtual Machines). The total number of MTP resources that are currently registered with the CallManager and are not in use (available). MTP Resource Utilization (%) A calculated percentage of the MTP resource utilization: Active MTP Resources * 100 / (Active MTP Resources + Available MTP Resources) MTP Out of Resources Incidents. It’s not fair to Cisco to tally up all the licenses in the table above and compare it to an OCS ECAL per user, although that’s how you had to buy those products until recently. I have not tried to do this by strictly relying on CUBE, which may supplement it, but it may also depend if you are using SDP transparency. 5 is that it supports outgoing call setup with Early Offer without requiring Media Termination Point (MTP).
