Genesys Cloud allows administrators to configure the trunk language for external and phone trunks, which determines the language used for incoming calls through those trunks. To set the trunk language, users with Telephony > Plugin > All permissions must navigate to Menu > Digital and Telephony > Telephony > Trunks, select either the External Trunks or Phone Trunks tab, choose the specific trunk to configure, access the General section under External Trunk Configuration or Connection Configuration, and select the desired language from the Language dropdown menu before saving. The configured language setting can be overridden at the Architect level if needed. This functionality applies to both external trunk and phone trunk configurations.
