Flow Builder
Text-to-speech preview
The Play Audio and Collect digits nodes now include a built-in text-to-speech (TTS) preview. This enhancement allows you to listen to your TTS messages directly from the configuration panel or by hovering over the node in the flow editor, making it easier to fine-tune automated audio prompts.
Dialer campaigns
Post Call Rating for Dialer calls
The Post Call Rating feature is now supported for Dialer campaign calls. You can enable this feature during campaign setup on the Add campaign page or by specifying the survey_enabled parameter when creating or updating campaigns via the API.

Contact redial status and webhook support
A new Contact Status API and webhook object (redial_status) provide insight into redial logic for unanswered contacts. You can now track how many redial attempts have been made, when the next attempt is scheduled, and whether the last dial attempt is final. Redial status is available in the dialer.call.ended webhook and in Extended Call Details: Voice.

Integration with Etisalat Safecall
A new integration with the Etisalat Safecall service is now available to support UAE DNCR compliance. When this feature is enabled, outbound calls to UAE numbers (+971) are automatically checked in real time against the Etisalat DNCR. Calls to registered numbers are blocked, and all calls are blocked by default if the DNCR verification service is unavailable. Admins receive on-screen alerts when service interruptions occur.
