Claude gives it a small nod at 14, while ChatGPT and Perplexity score it 0. When it does get mentioned, it's spread thinly across topics like call analytics and transcripts, best AI voice agents in 2026, multilingual support, general platform roundups, and cost-per-minute comparisons — each at 1 of 3 answers.
