Pricing Scenarios

  • Článok

Prices for Azure Communication Services are based on a pay-as-you-go model. The prices in the following examples are for illustrative purposes and may not reflect the latest Azure pricing.

Voice/Video calling and screen sharing

Azure Communication Services allows for adding voice/video calling and screen sharing to your applications. You can embed the experience into your applications using JavaScript, Objective-C (Apple), Java (Android), or .NET SDKs. Refer to our full list of available SDKs.

Pricing

Calling and screen-sharing services are charged on a per minute per participant basis at $0.004 per participant per minute for group calls. Azure Communication Services doesn't charge for data egress. To understand the various call flows that are possible, refer to this page.

Each participant of the call will count in billing for each minute they're connected to the call. This holds true regardless of whether the user is video calling, voice calling, or screen-sharing.

Calls charged with precision to a millisecond. For example, if a call lasts 30 seconds, the charge will be $0.002.

Pricing example: Group audio/video call using JS and iOS SDKs

Alice made a group call with her colleagues, Bob, and Charlie. Alice and Bob used the JS SDKs, Charlie iOS SDKs.

  • The call lasts a total of 60 minutes.

  • Charlie left the call after 43 minutes. Charlie used audio and video for the duration of time he participated (43 minutes).

Cost calculations

  • Two participants x 60 minutes x $0.004 per participant per minute = $0.48 [both video and audio are charged at the same rate]
  • One participant x 43 minutes x $0.004 per participant per minute = $0.172 [both video and audio are charged at the same rate]

Total cost for the group call: $0.48 + $0.172 = $0.652
