The integration between PrivateServer Appliance and the Cisco Unified Call Manager Business Edition version 8.6.2 (from now on shortly CUCMBE) is made possible by setting up a SIP Trunk. Both the appliances can speak SIP, both work out the UDP transport protocols and the G711/ulaw codec and that's mostly all we need to start.

We'll see how to configure both CUCMBE and PrivateServer to make this link possible and running.
