- Base UC around an IP PBX – this allows voice communications to be driven over IP and the internet and allows the integration of voice with other IP communication based services such as email, instant messaging and all these “web 2.0” channels.
- Ditch the PBX altogether and go for software platform such as Microsoft Lync or IBM Lotus Domino. For small SMBs this can be a pragmatic approach as such platforms can be procured as on-demand services. These are not just based on the platforms of large software vendors; many service providers are putting together their own on-demand UC services based on a range of underlying technology that suits them, but is largely irrelevant to the user
- Mobile network provider approach – again there is no traditional PBX involved. Mobile service providers are keen to grow their presence in organisations of all sizes and put themselves at the core of UC. This may involve the deployment of pico or femto cells
