Home Lab questions

[redbull88]

Hello all,

I have a a 2911 ISR I am using as my home router. I have recently come to possess a handful of 7962 phones. Working a day job as a LAN support team member for a large company I am somewhat familiar with Routers but not as well as switches.

I am currently a student studying and trying to learn more about these systems and want to build my own VoIP lab at home using the equipment I currently have. Spending only a few hours on the topic I have tried to figure out what is needed to run CME on my 2911 Router.  

Browsing different documentation and web pages from Cisco for different offerings I have no definite answers. At the least you could say i'm a bit overwhelmed with lots of information I don't fully understand. Which is exactly why I am here on the forum seeking advice from others who may have valuable information I am lacking which would help me achieve my end goal. 

Any help that can be provided will be greatly appreciated. Thank you for your time!

Hello,
Thank you for the reply. I have a specific subnet created for my voice traffic. Switch and Router configuration of my existing network have already been created. When trying to use the "telephony-service" command from global config it's not taking the command. Would the CME software have to be installed on the system separate from the IOS image? If so, how would I go about doing so?

You would need to enable the UC license on the ISR, and once it has been enabled, you can refer to the CME administration guide for all the tasks related to IP Phone configuration

Hello, Thanks for the reply.
I'm not seeing that the UC license is enabled on the system. Nor would I have a clue about how to achieve this. I'm also assuming anything more than an evaluation of this feature would cost an arm and a leg?
