Callers had to speak more firmly, and for longer, than they should have before the assistant would stop talking. The setting that decides how readily a caller can cut in had been turned down below the platform's own normal level, to stop background noise and a caller's own “mm-hm” from interrupting. It did stop those, and it also made genuine interruptions feel slow — you had to talk over your receptionist for a moment before it noticed.
It is back to the most responsive setting. The noise problem is handled where it belongs instead: short acknowledgements like “yeah”, “okay” and “mm-hm” are filtered out from the caller's audio, so agreeing with your receptionist no longer stops it mid-sentence while genuinely cutting in does — immediately.
Nothing changes about the opening notice: the recording disclosure at the start of every call still cannot be interrupted, and that is deliberate.
