Conference calls

Conference

Conference is out of the scope of this SDK. Because conferences are mainly done with Restful API. With above being said, I will provide some code snippets for your reference.

Create a conference

To create a conference: https://developers.ringcentral.com/api-reference/Call-Control/createConferenceCallSession If you are using SDK @rc-ex/core, you can do it like this:

const r = await rc.restapi().account().telephony().conference().post();

In the response of the above API call, you will get a r.session!.voiceCallToken!. As the host, you will need to dial in:

const confSession = await webPhone.call(r.session!.voiceCallToken!);

Invite a number to the conference

Make a call to the number you want to invite to the conference:

const callSession = await this.webPhone.call(targetNumber);

Then you can bring in the call to the conference.

await rc.restapi().account().telephony().sessions(confSession.sessionId)
  .parties().bringIn().post({
    sessionId: callSession.sessionId,
    partyId: callSession.partyId,
  });

Merge an existing ongoing call to the conference

Let's say an existing call session is callSession.

await rc.restapi().account().telephony().sessions(confSession.sessionId)
  .parties().bringIn().post({
    sessionId: callSession.sessionId,
    partyId: callSession.partyId,
  });

You can see that it doesn't matter how the call is created, it could be either an outbound call or an inbound call. You could create it on-the-fly or you can find an existing call session.

A live sample

https://github.com/tylerlong/rc-web-phone-demo-2 provides conference features. You may create conference, invite a number to the conference, merge an existing call to the conference, etc.
