I like how well it works and integrates with our existing Cisco infrastructure as well as other third part products that we use. Everything just seems to work.

What do you dislike about Cisco Unified Communications Manager (CallManager)? I would say if you need to make a configuration change, then it can become a challenge if you do not know enough about the system and what things will do. There are many menus within CUCM and you don't want to make a wrong change. I wish the UI was a little more friendly, it does seem a bit outdated. But, I get it, it works, so why change it. Additionaly, as everything Cisco, I do dislike the yearly suspport to pay to get any upgrades or to get a hold of Cisco technical support. Review collected by and hosted on G2.com.
