Managing Amazon Chime SDK Voice Connectors

What is an Amazon Chime SDK Voice Connector?

An Amazon Chime SDK Voice Connector provides Session Initiation Protocol (SIP) trunking service for your existing phone system. You can manage your Voice Connectors from the Amazon Chime SDK console and access it over your internet connection, or you can use AWS Direct Connect. For more information, see What is AWS Direct Connect? in the AWS Direct Connect User Guide.

Voice Connector outbound and inbound calling

After you create a Voice Connector, edit the termination and origination settings to allow outbound or inbound calls, or both. You then assign phone numbers to the Voice Connector. You can use the Amazon Chime SDK console to port in existing phone numbers or provision new phone numbers. For more information, see Porting existing phone numbers, Provisioning phone numbers, and Assigning and unassigning Amazon Chime SDK Voice Connector phone numbers.

Note

Voice Connectors support outbound calling in E.164 format and do not require an international dialing access code, such as 011. You pay a per-minute rate based on the destination country of the call. For a current list of supported countries, and the per-minute rate for each country, see https://aws.amazon.com/chime/voice-connector/pricing/.

Voice Connector groups

You can also create an Voice Connector group and add Voice Connectors to it. You can use Voice Connectors created in different AWS Regions. This creates a fault-tolerant mechanism for fallback if availability events occur. For more information, see Managing Amazon Chime SDK Voice Connector groups.

Logging and monitoring Voice Connector data

Optionally, you can send logs from your Voice Connector to CloudWatch Logs, and turn on media streaming from your Amazon Chime SDK Voice Connector to Amazon Kinesis. For more information, see CloudWatch logs for the Amazon Chime SDK and Streaming Amazon Chime SDK Voice Connector media to Kinesis.

Before you begin

To use an Amazon Chime SDK Voice Connector, you must have an IP Private Branch Exchange (PBX), Session Border Controller (SBC), or other voice infrastructure with internet access that supports Session Initiation Protocol (SIP). Make sure that you have enough bandwidth to support peak call volume. For information about bandwidth requirements, see Bandwidth requirements.

To ensure security for calls sent from AWS to your on-premises phone system, we recommend configuring an SBC between AWS and your phone system. Allowlist SIP traffic to the SBC from the Amazon Chime SDK Voice Connector signaling and media IP addresses. For more information, see the recommended ports and protocols for Amazon Chime SDK Voice Connector.

Amazon Chime SDK Voice Connectors expect phone numbers to be in E.164 format.
