The ability to have your phone with you at any time on your computer and not have a need for a desk phone is huge.

PS Patricio S. Governance, Risk & Compliance Lead Enterprise (\> 1000 emp.) 5/6/2016 "The best solution " 4.5/5 What do you like best about Cisco Unified Communications Manager (CallManager)? It is a very friendly solution for global companies. I implemented the cloud based solution after having several CM express servers around the globe and the experience is awesome. Really simple to update, or perform administration activities. If you understand all its components, it is a very useful tool for users who need access to corporate phone while travelling or changing locations very frequently. I had the chance to implement this platform twice always with good results, and pretty simple projects. Review collected by and hosted on G2.com. What do you dislike about Cisco Unified Communications Manager (CallManager)? The only issue I saw during implementations is that calls for each country must be configured from scratch. It would be very useful if CISCO could develop standarized templates according each country to reduce testing phase activities. Review collected by and hosted on G2.com. Recommendations to others considering Cisco Unified Communications Manager (CallManager): It is really interesting if you can educate users from scratch in the whole suite.

There is sometime a bit of lag between the time that a message is left and it appearing in one's email inbox.
