Intermittent SIP failures with the Realtime API

Hi @Inobrega, thanks for sharing this. A few similar intermittent SIP/Realtimes cases have been reported recently, especially around “normal temporary failure” responses that appear inconsistently even with unchanged configs. The tricky part seems to be that the same project and endpoint can succeed one moment and fail the next, which makes it hard to isolate from the customer side alone. A similar case has already been escalated internally, and the engineering team is taking a closer look at it. In the meantime, collecting full SIP traces, call IDs, response codes, and timing correlations has been the most useful data for narrowing patterns down. If others here are seeing the same behavior, adding details publicly will probably help connect the dots faster. -Mark G.
