Apologies for asking an off topic question, our company is thinking of implementing telecom expense management (TEM) to control costs and avoid unplanned budget expenses in our organization. We are trying to sort out its benefits to see if it is feasible/worth the budget. Apparently this system can analyze the communications spending, improve reporting and accountability, and provide visibility into how the organization can maximize value from its communication services. How can we validate this? Is there anyone here who has the same system in their organization?
