The Amazon Chime SDK WebRTC media API endpoints are hosted in the US East (Northern Virginia), US West (Oregon), Europe (Frankfurt) and Asia Pacific (Singapore) AWS Regions. These API endpoints allow you to create WebRTC sessions in other AWS regions. For more information, refer to the Available Regions section in the Amazon Chime SDK Developer Guide.

Q: Are Amazon Chime SDK WebRTC media sessions available in AWS GovCloud (US)?

Yes. The Amazon Chime SDK WebRTC media API endpoints and media regions are available in AWS GovCloud (US) Regions.  For more information, refer to the Available Regions section in the Amazon Chime SDK Developer Guide.

Q: What are scaling limitations of a WebRTC media session?

Q: How many WebRTC media sessions can I have at the same time?

The Amazon Chime SDK allows you to create WebRTC media sessions which can host up to 250 attendees with 100 webcam video streams, and two shared content streams. Each client application can independently select and display up to 25 webcam video streams.

By default, each AWS account is limited to 250 simultaneous WebRTC media sessions. This limit can be adjusted by submitting a request through the AWS Console – Service Quotas.

Q: What audio sharing specifications are supported by WebRTC media sessions?

The Amazon Chime SDK for JavaScript supports mono and stereo audio at the highest sample rate supported by the device and browser, up to a maximum of 48kHz. Audio is encoded with bitrates up to 128kbps stereo / 64kbps mono using the Opus codec. The Amazon Chime SDKs for iOS and Android support mono audio up to 48kHz, with bitrates up to 64kbps using the Opus codec.

Q: What video specifications are supported by WebRTC media sessions?

The Amazon Chime SDK for JavaScript supports video resolutions up to 1280x720 at 30 frames per second without simulcast, and 15 frames per second with simulcast. The Amazon Chime SDK for iOS and Android support video resolutions up to 1280x720 and 15 frames per second, however the actual framerate and resolution is automatically managed by the Amazon Chime SDK.

When active, video simulcast sends each video stream in two different resolutions and bitrates. Clients which are bandwidth constrained automatically subscribe to the lower bitrate stream. Video encoding and decoding uses hardware acceleration where available to improve performance.

Q: What content share specifications are supported by WebRTC media sessions?

Content sharing supports pre-recorded content video up to 1920x1080 at 30 frames per second, and stereo audio up to 48kHz at 128kbps (64kbps mono). Screen capture for content sharing is at the resolution of the screen or window being captured, and up to 30 frames per second, but may be limited by the capabilities of the device and browser.

Q: What media capture options are supported and how can I switch from the default behavior for the media capture pipeline?

The media capture pipeline with the Amazon Chime SDK provides the ability to capture a single stream of the active speaker video along with the combined meeting audio. Alternatively, you can configure APIs to capture individual video tile streams, with a separate combined meeting audio or stream, or capture only the combined meeting audio with no video. You can also use SourceConfiguration to select specific attendee video streams to capture, and do not need to capture all individual video streams.

Q: In which regions can I use media capture pipeline feature?

API endpoints for media capture pipeline are hosted in the US East (Northern Virginia), US West (Oregon), Europe (Frankfurt) and Asia Pacific (Singapore) AWS Regions. These API endpoints allow you to create media capture pipelines in other AWS regions.

Q: Is there any prerequisite before creating MediaCapturePipeline?

MediaPipeline needs service linked role for mediapipelines.chime.amazonaws.com to be created in the caller’s AWS account before creating media pipelines.

Q: What policies will the new service linked role have?

The new service linked role will have permissions to GetMeeting, CreateAttendee and DeleteAttendee APIs for an Amazon Chime SDK Meeting

Q: Can I get a history of ChimeSDKMediaPipeline API calls made on my account for security analysis and operational troubleshooting purposes?

Yes. To receive a history of ChimeSDKMediaPipeline API calls made on your account, you simply turn on CloudTrail in the AWS Chime SDK Management Console and filter the event source to be chime-sdk-media-pipelines.amazonaws.com.

Amazon Voice Focus is available as an Amazon Machine Image (AMI) which can be used outside of the Amazon Chime SDK for synchronous workloads to help reduce noise in real-time speech capture and streaming, or for asynchronous workloads such as enhancing archived speech recordings. For more information, please contact us. 

PSTN Audio

Q: Which countries can I make calls to when using PSTN Audio in the Amazon Chime SDK?

To connect attendees to a meeting session using a telephone, you can make calls from your meeting application to over 100 countries. Please see our pricing page for the most up to date list of countries.

Q: Which countries does the Amazon Chime SDK PSTN Audio have telephone numbers for?

Please see our pricing page for the list of countries where Amazon Chime SDK PSTN Audio is currently available.

Q: Can I keep my existing Direct Inward Dial (DID/DDI) and toll-free phone numbers?

Yes. You can port most DID/DDI and toll-free numbers to the service for those countries where Amazon Chime SDK PSTN Audio is available.

Q: If I have an on-premises phone system or contact center, can I use Amazon Chime Voice Connector with PSTN audio applications?

Yes, you can configure a Voice Connector to your on-premises voice infrastructure that supports the Session Initiation Protocol (SIP). You can choose to route calls to and from the Voice Connector using the CallAndBridge action in the PSTN audio application you build. For example, to route incoming calls from the PSTN to your Voice Connector, specify the Voice Connector or Voice Connector Group ARN in the CallAndBridge action that you return in your AWS Lambda function. To route incoming calls from your Voice Connector, first provision a SIP rule in the Amazon Chime SDK console to invoke your PSTN audio Lambda function. Next, specify an E.164 phone number, Voice Connector/Voice Connector Group ARN in the CallAndBridge action that your return. The call will route to the PSTN if you specify a E.164 phone number. If you specify a Voice Connector/Voice Connector Group ARN, the call will route to a Voice Connector.

Q. How can I connect a PSTN audio call to a call center agent or an enterprise PBX user?

The Call&Bridge action connects a PSTN audio call to an external call center or a PBX. If your target telephony environment supports SIP, you can provision a Voice Connector and build a SIP trunk between your call center, PBX, SBC and Amazon Chime SDK; then you can specify your Voice Connector and the SIP extension as a CallAndBridge target. Alternatively, you can specify a E.164 phone number as a bridged end-point; in this case, the call will be connected over PSTN. In case of SIP bridging, you also can pass the attached data in the SIP header.

Q. Do I have to always record the entire call?

With call recording, you have a choice to record the entire call or only specific parts of the call, or not to record anything at all. Depending on your use case, you can choose to record inbound and/or outbound audio tracks of one or several call parties, commonly referred to as “call legs”. You can also start, stop, pause, and resume the recording of each call leg at the specified times during the call.

Q. Can I control when to start, stop, pause, and resume the recording for just a portion of the call?

You can start and, subsequently, stop call recording at any point in time during the call; upon hanging up, the recording is stopped automatically. Please note that for each call leg you can start and stop the recording only once within the duration of the call. If you need to interrupt the recording of a call leg for some period of time and then continue the recording again, you must use pause and resume actions. The PauseCallRecording action pauses recording of a call leg. Pausing does not stop the call recording process or change the length of the call; instead, a brief tone is played when the pause is started and silence is recorded for the duration of the pause. You can pause and resume the recording multiple times for the duration of the same call leg.

Q: What is captured in the call recording file if the recording was paused?

Each time you pause call recording, a brief tone is played when the pause is started and silence is recorded for the duration of the pause.

Q: What type of call recordings audio files do I get?

The calls are recorded in the open WAV format. If you choose to record both incoming and outgoing tracks of a call leg, it will result in a stereo recording; if you record only the incoming or the outgoing track then you will get a mono recording.

Q: How many recording files do I get per call?

You will have one WAV file per recorded call leg. Here are a few examples. (a) For an IVR call, where there is only one leg to record, you will get 1 media recording WAV file. (b) For a contact center call with one agent-to-agent transfer with agent call leg recording, there will be two agent-side call legs and you will get 2 media recording WAV files. (c) For a contact center call with only the caller’s leg recorded you will get 1 media recording file regardless of the number of transfers on the call center side.

Q: How can I find my recordings?

The call recording destination is recorded in the CDR (Call Detail Record). For all recording files written to your Amazon S3 bucket, the file name and the S3 object metadata will contain identifiers such as call id and transaction id, which you can use to identify the recordings for further processing.

Q: Can the callers turn voice focus on and off?

With the PSTN audio application’s VoiceFocus action, you can turn the noise reduction on and off for each individual call participant (per call leg). For example, you can allow call participants to turn the noise reduction on and off for themselves by using touch-tone commands, just like “mute/unmute” operation.

PSTN Audio Billing & Pricing

Q: How will I be billed when I use the PSTN audio feature?

When you use the PSTN audio feature, you will be billed for the following (as applicable):

Q: What are Amazon Chime SDK proxy phone sessions?

Amazon Chime SDK proxy phone sessions let you provide two users with a shared phone number to communicate via voice or text for up to 12 hours without revealing personal phone numbers. When users call or message the provided phone number, they are connected to the other party and their private phone numbers are replaced with the shared number in Caller ID. Personal phone numbers are not displayed, a method often called number masking. Numbers are provided based on criteria the developer chooses, including geolocation and whether they want a phone number that has never been used for the same users before, or one that has. Proxy phone sessions help protect user privacy and keep transactions on your service. Numbers are available on-demand, so developers don't have to calculate how many numbers they will need for different locations, or pay for extra numbers they do not use.

Q: What are the use cases for Amazon Chime SDK proxy phone sessions?

Proxy phone sessions are commonly used in the on-demand economy. For example, a developer for a food delivery service can provide delivery drivers an option to call or message customers through a proxy phone number provided by Amazon Chime SDK to get information like a gate code. This same number can be used by the customer, so the private phone numbers of the driver and the customer are protected.

Other use cases include telemedicine, dating services, and outbound call centers.
