My calling was limited to calls to/from the softphones. I don't (yet) have a SIP trunk and as said previously I don't have a router so there's no analog trunks either. Because I'm not super keen on installing/uninstalling random software on my main workstation, I quickly spun up a Windows 7 VM to act as my host for the softphone clients. My lack of familiarly with the CUCM/CUC interfaces meant I had to concentrate mostly in that area.Īs far as phones, I opted to go with softphones so that I could scale up/down the number of phones quite easily. There's such limited IOS command line work in the CCNA Voice that I didn't want to go through the effort of getting a router going that was running Communications Manager Express. The premise of the lab is really to allow me to study the CUCM and CUC interfaces.

Cisco Unified Communications Manager (CUCM).

This post is about the tools and methods I used to build a small lab to support my studies. Since I now need to talk intelligently about Cisco voice solutions, products, and architectures, I decided to go through the CCNA Voice curriculum as a way to establish some foundational knowledge. Now that I'm in a job role where I'm expected to be somewhat of a jack-of-all-trades, I can no longer avoid learning voice :-) For a long time I've focused on just the underlying network bits and left the voice 'stuff' to others. I've been working on something that at this point in my career I never thought I'd be doing: another Cisco Certified Network Associate (CCNA) certification.
