Amazon Chime SDK Voice Connector review
A focused voice connector for PBX-to-PSTN calling within the AWS ecosystem.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Amazon Chime SDK Voice Connector is a managed SIP trunking service for organizations with existing PBX, session border controller, or other SIP-compatible voice infrastructure. It handles inbound and outbound PSTN calling, phone-number provisioning and porting, and connectivity through the internet or AWS Direct Connect. Administrators can configure connectors through the Amazon Chime SDK console and APIs, making it a focused option for connecting established voice systems to AWS services and the public telephone network.
Pricing follows usage rather than a fixed monthly plan. Published rates vary by destination, phone-number type, and optional services, so the service fits teams that can evaluate calling patterns and related features individually. There is no free plan. The paid model covers a broad set of voice functions, including number management, SIP trunking, recording workflows, and call analytics configuration through Amazon Chime SDK APIs.
Its strongest fit is the AWS ecosystem. Integrations include AWS Direct Connect, Amazon CloudWatch Logs, Amazon Kinesis Video Streams, Amazon S3, Amazon EventBridge, and AWS Lambda. Voice Connector groups support regional failover, while SIP and SIPREC workflows support recording and media streaming can connect with Kinesis Video Streams. Choose it when existing SIP infrastructure and AWS services are central to the deployment. Organizations seeking a standalone web calling product, a free tier, or a simple fixed-plan service should consider a different type of voice API.
