# API Support

Salesforce is committed to supporting each Open CTI version for a minimum of three years from the date of its first release.

**important:** Open CTI is in maintenance mode and is scheduled for retirement in February 2028. No new features or enhancements are being added to Open CTI. Effective immediately, Open CTI is deprecated and unavailable for newly created Agentforce Service orgs. To ensure long-term compatibility and access to the latest innovations, we recommend transitioning your development efforts to Salesforce Voice. For more information, see this [Knowledge Article](https://help.salesforce.com/s/articleView?id=005306437&type=1), [learning map](https://help.salesforce.com/s/articleView?id=service.cti_migrate_map.htm), and [developer migration guide](/docs/service/api-cti/guide/migrate-cti.html).


To improve the quality and performance of Open CTI, versions that are more than three years old might not be supported.

When a Open CTI version is scheduled to be unsupported, a no-longer-available notice will be given at least one year before support for the version ends. Salesforce will directly notify customers using Open CTI versions that will no longer be available.
