What's New in Coolblack KI Telefonassistent
3.0.2
September 8, 2026
Two improvements for premium voices: the agent now understands callers who start speaking right after the greeting — previously the beginning of the sentence could be lost and the agent stayed silent. Call transcripts also include both sides again: the agent's replies were missing, which made transcripts and summaries look incomplete.
