Hi, we are a Mitel partner based out of Australia and we are planning to develop few industry specific applications/integrations to Mitel MiVoice Business and MX-One solutions. We are new to Mitel CloudLink. For each of the use cases, we would like to create mock ups or proof of concept applications. Could we do these using self-assessed applications until we are ready with full blown functionalities in each case? If so, how do we register & test self assessed applications please?
