The main advantages of integrated communication are flexibility, ease of use, and cost savings. There is no need to make big initial investments in developing and deploying a platform. Instead, you pay an ongoing service fee. Also, it is easy to add services with a cloud-based solution.
However, some companies prefer an integrated communication solution. In this case, all the hardware is stored on site, which can include racks, power supplies, and cooling systems to manage the virtual PBX phone system. For large organizations that prioritize a bespoke solution and already have a lot of IT resources that will help with refinement and improvement, a leading UC would be a good fit.
