In a strictly lab environment, I was able (with the help of some very knowledgable instructors and friends) to connect the VM version of Cisco Unified Communications Manager (CUCM) to a Cisco Unified Communications Manger Express (CUCME) which was performing its routing functions as a router on a stick (ROAS). I also used a single voice switch and two Cisco IP phones, one 7940 and one 7960.

The router and switch configurations are provided in the following tabs.

Here is a simple logical diagram of the network:
CUCM-CME-ROAS

In order to make this work, I had the CUCM VM running on my laptop using VMWare Player. The IP address of the CUCM VM is 192.168.15.10. My VM's NIC is bridged to the physical network and is set to replicate the physical network connection state. I used only the LAN "VirtualBox Bridged Networking Driver Miniport." All other VM and CUCM setting are standard.

I have disabled all laptop network adapters except the Local Area Connection and VirtualBox Host-Only Netowrk. Both VMWare VMNet1 and VMNet 8 are disables and my wireless is turned off. My LAN NIC is set with IP address 192.168.15.15.

Within the CUCM, I have one Publisher running and no other servers running at this time. All standard settings are used. I have defined one Cisco 7940 phone to run with SCCP and two lines defined (5001 & 5002). I have one Inter-cluster Trunk (ICT) to the IP address of the CME. I have one route pattern defined that points "[1234]XXX" to the CME ICT. The use of 1-4 in the first digit allows a future connection to the other labs in the classroom.

Cisco Configuration Professional

CUCME Menus within CCP


Cisco Configuration Professional was created to configure all major aspects of the CME router. It enables simple configuration of the Unified Communicaiton fetatures and configurations (as well as other router based systems).

By default, CCP attemps to connect to the router using Telnet and HTP, which are both clear-test protocols. Of course, secure connections are always better. By simply checking the Connect Securtly checkbox in CCP it now uses SSH and HTTPS to connect to and configure the CME router.
