Resolved

Between 1:45 PM PDT Oct 24th and 4:50 PDT Oct 25th, a permission issue with openAI speech-to-speech model caused calls using speech-to-speech agents to fail or go silent. Access has been restored and speech-to-speech calls are working normally. Agents using the standard (cascading) setup were not affected.
