The VTListenOptions model defines how the application expects to join a conference as a listener, in terms of media preference. The VTListenOptions model specifies:



conferenceAccessToken: String?

The conference access token that is required to join a protected conference if the conference is created using the Create REST API. If the conference is created using the create method, the token is managed by the SDK and is not visible to the application users. For more information, see the Enhanced Conference Access Control document.

Returns: String?


maxVideoForwarding: Int?

Sets the maximum number of video streams that may be transmitted to the joining participant. The valid values are between 0 and 4. In the case of providing a value smaller than 0 or greater than 4, SDK triggers the videoForwarding error.

Returns: Int?
