Crayon Singapore has been using the Axiom Teams Connector for our Team’s collaboration across the region. In fact our cloud desk is operational on this service managing conversation and calls with hundreds of our partners in Singapore. We estimate that we save at least 50% of our communications costs by switching to this service. Thank you Pang Ngean Lam and team. Really happy to see this on the Microsoft Partner Exchange. Kudos.
