Financial services companies that have embraced Microsoft Teams for messaging and meetings must take one critical next step to achieve full benefits of Unified Communications-as-a-Service (UCaaS): integrating calling. They do not, however, need to adopt Microsoft Teams Phone System. In fact, there’s a better option: integrated calling services from a UCaaS provider. This option provides them with the best opportunity to minimize telecom costs, maximize reliability, compliance, and security; and provide access to advanced calling features. If you are looking to improve the overall communications experience by adding calling to your Microsoft Teams environment, you should evaluate the benefits of integrating UCaaS with the Microsoft Teams app.
