• There is some brand confusion that exists between Cisco communication products. This is more relevant to the support personnel and engineers that would be making decisions to implement the product. Cisco has their Spark/WebEx platform that provides collaboration/communication functionality and more to the end users. Cisco has stated at some conferences that I attended that they are committed to maintaining and developing the Cisco Jabber platform still so that is very promising since the product serves different needs.
• Cisco Jabber is a little complex to implement properly in your environment. The larger the communication cluster the more complicated it can become. There are also some additional features like persistent chat that require extra resources like a standalone database for persistent chat.

• Not cloud-based, and there's no mobile app.
• The ability to email voicemail messages would be great.

• Jabber has provided a very functional alternative to our company to Lotus Sametime. We had been using Sametime for years, and as we were moving out of the Lotus/Domino ecosystem, Jabber has provided a replacement with the chat system, but also means to do voice and video calls.
• Although handy, intensive usage of Jabber can be a curse for a company (including ours). Every information stored in Jabber is only available to the two people involved in the conversation. Without a proper knowledge management strategy, this can mean that a lot of valuable information can be shared privately as peer-to-peer conversations, and not available to people who need it.
• Another downside of Jabber is that it can multiply stress for some people, who can be contacted very often, and be interrupted at critical moments. This can introduce additional context switching, and reduce the productivity of some people.
