Video Conference Dial in

Using the Vonage Video API and Voice APIs, you can create a conference video call which supports dial in.You can connect phone calls to a video call session, which means that a user can join a video call session with an audio-only stream by calling from their phone.

In this project, you’ll use both the Video API SIP Dial-out feature and Voice API Dial-in feature to connect the video session and voice call.The project uses Vonage Cloud Runtime, removing the need to manage servers and hosting. Visit the developer portal to view documentation on how it works.

The project also provides APIs that can be used as a connector between your Vonage Video application and Dial-In Voice call.

APIs:

Authorization: VONAGE JWT

Get the Authorization Token for all the API Requests:

POST: ${ApplicationHost}/auth-token  
BODY: {apiKey: ${vonage-apiKey}}  
Response Sample: {authToken: ${VONAGE JWT}}

Generate Video Token for joining a Video Session:

GET: ${ApplicationHost}/room/:roomName  
QUERY: Optional (role="publisher" OR "subscriber" OR "moderator")  
HEADERS: Authorization: ${VONAGE JWT}  
Response Sample:{    
    sessionId: xxx,    
    videoToken: xxx,    
    roomId: xxx,    
    pinCode: xxx
}

Pin Code is used to verify if a Voice call is allowed to join a Video session. To get the pincode:

GET: ${ApplicationHost}/pin-code/:sessionId  
HEADERS: Authorization: ${VONAGE JWT})  
Response Sample : {pinCode: xxxx} 

To hang up the Voice Call(s) in a video session:

POST: ${ApplicationHost}/hang-up/:sessionId  
HEADERS: Authorization: ${VONAGE JWT})  
BODY: Optional ({connectionId : xxxx})
