Notes about billing

Audio and video call fees = unit price of audio tracks × audio call duration + price of aggregate resolution tier × video call duration

1. The duration of a call is the sum of the subscription duration of each client to each video track. The duration of each call is metered in seconds and rounded up to the higher number (minute) for billing.
2. The media track types and track specifications are determined by the configurations of the publisher client. RTC supports two media track types (audio and video) and four track specifications (audio only, 480p video, 720p video, and 1080p video).
3. Alibaba Cloud RTC generates the bill for the current day at 02:00 (UTC + 8) the next day. You can view the bills on the RTC console.
4. The screen sharing feature is implemented in a separate video track. When the screen sharing feature is used, you are charged for an additional video track based on the track specification. The specification is determined by the screen sharing resolution parameter you have configured.

Voice Call Billing

Unit Price of Audio Tracks: If clients only subscribe to audio tracks, you are charged based on the specification of the audio tracks.
Voice Call Duration: Metered from the time a client subscribes to an audio track until the client unsubscribes from all audio tracks. You are only billed once for subscriptions to the audio tracks in the same channel.
● If the media type configured on the publisher client is video, but clients only subscribe to audio tracks, you are only charged for the audio tracks based on the specification of the audio tracks.
● If clients subscribe to audio and video tracks, you are only charged for the video tracks based on the specification of the video tracks.

Video Call Billing

Unit Price of Video Tracks: If clients only subscribe to video tracks or subscribe to both audio and video tracks, you are charged based on the specification of the video tracks.
Video Call Duration: The duration of a video call is metered from the time a client subscribes to a video track until the client unsubscribes from all video tracks.
● If the media type configured on the publisher client is video, but users turn off their cameras during a video call, you are still charged for the video tracks.
● The duration of a video call is the sum of the subscription duration of each client to each video track.
