The small figure is the place among ranked models. The cascade is not ranked.
Phonic v1 1.60s, Azure Realtime 1.66s at the median.
Azure Realtime is more reliable, by 2.4 points. Azure Realtime passed 58 of 82 scenarios on all three runs, and Phonic v1 passed 56. A scenario only counts when every run of it passed.
For a phone agent, Azure Realtime, since it gets more scenarios right on every run. Azure Realtime is ahead on reliability, success rate, agent responses, data accuracy, interruption and cost, and Phonic v1 on stalled calls and response time.
Azure Realtime, by 8.7 points. Azure Realtime saved everything exactly right on 86.1% of the calls that save data, and Phonic v1 on 77.4%. On Appointments, 94.2% against 98.2%. On Medicare, 65.2% against 25.0%. A call counts only when nothing is missing, wrong, extra or saved twice.
No. Phonic v1 starts replying 0.05s sooner at the median. Azure Realtime takes 1.66s at the median and 2.22s at p90; Phonic v1 takes 1.60s and 1.88s. Both are measured on the call audio, from the caller finishing to the agent starting to reply.

Cekura ran both as the whole agent in the same open-source Pipecat pipeline, with the same prompt, tools and connection. A simulated caller worked through all 82 scenarios on live calls, three times each, 2,952 calls across the benchmark. A call passes only when the agent said the right things and saved the right data.
