Phone Number Rotation
Agent campaigns can now rotate caller IDs on retries. With Phone number rotation enabled, every subsequent call to the same user uses a different agent number until each number in the pool has been used once for that user - so a contact who didn’t answer one number gets the retry from another, not the same one again. Requires two or more agent numbers on the campaign. Enable it from the Phone number rotation toggle under Advanced on the Schedule step of the campaign wizard, or set phone_rotation.agent: true in app_config.
Voice Cloning API
Added the Voice Cloning API: create a saved voice from a reference clip with POST /voices/create, then generate speech with POST /voices/clone and its voice_id. The model is cross-lingual across 12 supported languages. Requires the text_to_speech_voice_cloning capability on your subscription; generation is billed per character of text.
