Optimum: "The best or most favourable point, degree or amount. The greatest degree or best result obtainable under specific conditions"
Welcome to Obsidian
At Obsidian, our definition of an optimum solution has two very distinct meanings. Firstly, over the last 10 years we have identified and developed a suite of converged communication services, each of which is the best of its kind. Secondly, these services all have a common theme. Working together or individually, they enable our customers to communicate in the optimum way.
We are dedicated to achieving significant and sustainable communications cost savings for both commercial and public sector organisations. Each of our managed service offerings has been designed and developed with the sole aim of reducing cost, increasing efficiency or guaranteeing compliance.
