Amazon Chime Voice Connector adds the US West (Oregon) AWS region and redundant call routing
Amazon Chime Voice Connector, the AWS SIP trunking service that can save you over 50% on your calling costs, now supports the US West (Oregon) region and redundant call routing across multiple regions for higher availability and disaster recovery. With this feature, companies can continue to place and receive phone calls even if access to an individual AWS region fails or performance degrades. With Voice Connector, customers have the option to enable inbound calling, outbound calling, or both.
