Amazon Chime Voice Connector features

SIP Trunking


Standard-based Session Initiation Protocol (SIP): Compatible with the leading SIP-based Private Branch Exchanges (PBXs), cloud calling solutions, and Session Border Controller (SBCs).

Outbound Calling: Low, per-minute rates for calling from your business phone system to over 115 countries. You can use Amazon Chime Voice Connector for just outbound calling or with inbound calling.

Inbound Calling: Callers can reach your phone system extensions directly through Direct Inward Dial (DID) and toll-free telephone numbers. You can use Amazon Chime Voice Connector for just inbound calling or with outbound calling.

Elastic Scaling: Meet all your call volume needs, including unexpected or seasonal spikes. You no longer need to purchase bursting capacity or over-provision concurrent call paths.

Pay-as-you-go pricing: Pay only for what you use. You pay by-the-minute for inbound and outbound calls and monthly for phone numbers (for inbound). There is no charge for concurrent calls or encryption. When you use Amazon Chime Voice Connector to dial into Amazon Chime meetings or call Amazon Chime Voice Connector numbers, these calls do not incur per-minute charges. Please see our pricing page.

Quality and Reliability: Amazon Chime Voice Connector supports fault-tolerant, cross-region inbound and outbound call routing to and from your phone system. In the event of loss of connectivity between an AWS region and your phone system, or if there is an issue with the Amazon Chime Voice Connector service in a region, calls will route to the other Amazon Chime Voice Connectors

Security and Authentication: You can use encryption to secure calls between your phone system and AWS. Amazon Chime Voice Connector supports TLS to encrypt SIP signaling and SRTP to encrypt media streams. You can choose between IP whitelisting and SIP Digest to authenticate SIP messages.

Cost-effective Network Access: You can access your Amazon Chime Voice Connector over AWS Direct Connect or your Internet connection. Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections.

Phone Number Management and Porting: You can manage your phone number inventory, order new numbers, and review pending transactions using the Chime console, AWS SDK, and AWS CLI. You can keep your existing phone numbers by having us port them from your previous service provider.

Setup: You can start using your SIP trunks in minutes using the Amazon Chime console or AWS SDK. There are no service orders needed and no trunk set-up charges. Use the AWS SDK to perform and automate common administrative tasks such as creating Voice connectors, setting parameters, and managing phone numbers for moves, adds, changes and deletes; for example, when on-boarding new employees.

Call Health Monitoring: IT and telecom managers can use Amazon CloudWatch to get a unified view of voice calling operational health that includes call completion rates and voice quality metrics. You can use CloudWatch to detect anomalous behavior, set alarms, visualize logs and metrics, automate actions, and troubleshoot issues to keep your voice calling running smoothly.

T.38 Fax Support: Amazon Chime Voice Connector supports the T.38 standard for transmitting facsimiles (fax) across IP networks. Using the T.38 feature, you can send and receive faxes using traditional fax machines connected to your phone system or directly through bulk fax servers. You can transmit faxes at speeds of up to three seconds per page when using Super G3 — which results in reduced calling charges versus slower transmission speeds.

Third-Party Emergency Services Support: You can use Amazon Chime Voice Connector to access emergency calling services from third-party providers, such as Intrado. Emergency calling services must be purchased and configured separately with the third-party provider as Amazon Chime Voice Connector does not include emergency calling or provide caller location information.

Phone Call Analytics


Voice Analytics: You can quickly build call audio analytics applications like transcription and sentiment analysis by integrating with Amazon Transcribe, Amazon Comprehend and other Machine Learning (ML) libraries. You can use Amazon Kinesis Video Streams APIs to retrieve the audio from your streams on a frame-by-frame basis to build real-time applications.

Flexible Deployment Options: Phone call analytics works with Amazon Chime Voice Connector SIP trunking or your SIP-based media recording (SIPREC)-compatible PBX or SBC. That means you can start building analytics applications right away regardless of your PSTN calling solution. To learn more, see the documentation.

Amazon Chime SDK Support


Audio Conference Dial-in: You can use Amazon Chime Voice Connector for dial-in for meetings that you create using the Amazon Chime SDK.

Application Integration: Use your own Interactive Voice Response (IVR) application to capture meeting PIN and passcode information to pass to the Amazon Chime SDK.

Phone Numbers: Create your own personalized meeting dial-in numbers. Toll-free and toll numbers are supported.

Proxy Phone Sessions

Protect user privacy and keep communication within your service: Amazon Chime proxy phone sessions allow you to enable your users to contact each other using the reliability of a phone call, without requiring users to share their personal phone numbers. This helps ensure they can connect regardless of internet connectivity or if they are signed in to your service, and allows you to control the time period when they can contact each other. Controlling when users can communicate helps protect user privacy because they cannot be contacted once the transaction is completed, improves service because out-of-session calls can be redirected to support agents, and helps keep financial transactions within your service.

Automated number management and scaling: Amazon Chime proxy phone sessions provide phone numbers on-demand from our phone number pool, so you do not have to build the complicated logic to ensure you always have the right numbers for each interaction. If you need a number to match the area code of a customer, we will provide one. If you want to reuse the same number as the user’s last session, that logic is built in. Likewise, if you want to make sure the number for your next session is different, that logic is built in as well.
