We had a production call where a subagent node called a custom tool, received a successful result, and then the conversation went completely silent.
The tool result should have moved the caller to the next node, but Retell did not log another LLM turn or any node transition. The call stayed silent until the inactivity timeout ended it.
We’ve found ~10 calls like this. Is this related to the outage?
Relevant sequence:
16:13:33 Tool call succeeded
16:13:33 Tool result indicated the flow should continue to scheduling
16:14:18 No activity for 0.75 minutes, closing call
