Abstract: One-action URL based communications and other services and management of such services through designated UIs are provided. In some examples, URL based calling may be enabled for different communication modes using existing web browsers, components, and protocols without requiring the end users to employ special hardware or software. Indeed, to initiate a communication session, a requestor may not even have to identify themselves, create a user account, or log in to a service. Subscribers of the service may be provided dashboard UIs to manage their communications, communication/profile configurations, and communicate with other service subscribers.
