Elto has 2 objects that that you need to be familiar with when you make calls. When you create a one-off dial, you create a DialSession. When the DialSession is started, a Dial is created, and initiated. The reason for this distinction is to allow you to specify a configuration that may be used for multiple dials, that can then be orchestrated by Elto without overrunning any concurrent call limits. When you make a one off phone call, the dial is started automatically, for web calls, the dial is automatically started once a user connects their browser/client. The endpoint returns a dial session ID. Once the Dial is created, you’ll get a webhook, in case you need to manage the Dial further.
