Contact Center v19.0
Contact center version 19.0 is available from September 15, 2025.
This version includes these changes.
| Change | Applicable Telephony Models |
|---|---|
Migrated from SSM parameter store to AWS Secrets Manager. Previously Service Cloud Voice used SSM parameter stores to store certificates and configurable values. In Contact Center version 19.0 and later, these values are stored in Secrets Manager. Lambda function environment variables now include the Secrets Manager name. For preexisting contact centers that upgrade to Contact Center version 19.0 or later, SSM parameters automatically move to Secrets Manager. For new contact centers on version 19.0 or later, certificates and configurable values are stored in Secrets Manager by default. |
|
| Updated the Node.js runtime to version 22 for our Lambda functions to meet Amazon's requirements. This update brings several helpful changes, including better support for loading ECMAScript modules, built-in WebSocket support for real-time applications, and performance improvements for network operations. |
|
| Introduced Callback as a disconnect reason for CTRSync (Contact Record Sync). |
|
| Refined the IAM policy for SCVSSMAccessPolicy to replace the broad wildcard (*) for SSM with specific action on SCV-created resource ARNs to enhance security. |
|
| Made CTRData Sync Lambda enhancements to exclusively process contact records (previously called contact trace records or CTR) from voice channels. |
|
| Made an update to locate the correct outbound number associated with the specific messaging channel. |
