Configuring Presence call-lists in CUCME is fairly easy and can be done in a few simple steps. Activating this feature will allow the configured watchers to view the status (on/off hook, line busy, etc.) of the designated presentities. Now, Presence on CUCME is not as granular as it is on CUCM, you are not able to setup different Presence groups to allow some people to watch particular extensions, but not others. You have to keep that in mind when setting up who is the watchers and presentities are.
I have been contacted a few times by people that are running into problems getting their PSTN phone working in their home lab. This can be a little tricky, especially if you are just starting out in your CCIE Voice studies.
Your PSTN phone is going to rely on CUCME as well as very heavily on voice translation rules and profiles. If you are not familiar with either of these I would highly recommend reviewing the CUCME Admin Guide before starting to set up the PSTN portion of your home lab.
In my home lab I have a Cisco 2811 acting as my PSTN-WAN router. I have this 2811 as well as a 7961 IP phone connected to my Cisco 3560 switch. Below I will outline my 3560 and 2811 configurations that are relevant to getting the PSTN phone registered and assigned its configured numbers. I am assuming that you have already configured the PRI portion of your PSTN-WAN router.
Configuring CUCME is really, really easy. At least a really basic, phones register and can call each other, CUCME configuration is really, really easy. In this post I will help you get your phones registered to your CUCME router, and get their firmware updated to whatever release you downloaded.
What you will need:
A couple Cisco IP phones (IP Communicator or IP Blue will work just fine)
A router and switch with network connectivity between each other (see: CUCM Network Configuration)
A computer running a TFTP server, connected to the above router/switch
CUCME files (download here : You must have a Cisco CCO Account)
I know that Cisco has a very nice SRND & Administration Guide for CUCME, but I have found at time searching through them can be a little challenging when you are just wanting to get your equipment up and running so your phones can register. I am not sure how many parts this series of posts will include, but I am planning on starting with a new router with no configuration and going from there.
Here is the equipment I will be using during this series of articles:
2811ISR router running IOS c2800nm-spservicesk9-mz.124-24.T2
Catalyst 3550 switch running IOS c3550-i5q3l2-mz.121-22.EA8
Cisco 7940 IP phone
Cisco 7912 IP phone
Cisco 7970 IP phone
Laptop for a TFTP server, also running Cisco IP Communicator
