We looked at various systems and Avaya came up tops in all of the reviews. We did some research and contacted other organisations to ask what they had and Avaya came out on top every time. We also contacted some of Siebert’s customers to ask how their implementation and installation had gone and were very satisfied with the reports we had back. I was impressed by the professionalism and the detail of the project plan and also the assistance we were given in setting up the system. Senior Finance & IT Officer - Housing Assocation.
