Call Lifetime Controls
Re-engage callers who go quiet, and cap how long any call can run — two flow settings that stop calls from getting stuck.
Two flow-level settings now control how and when a call ends on its own — find them under Flow Settings → Call lifetime.
Inactivity handling
On by default. When the caller goes quiet after the agent speaks, the agent checks in — "Are you still there?" — and ends the call politely if there's still no response. The early checks are short, LLM-generated nudges that adapt to the conversation's language; the final check speaks a fixed goodbye and hangs up. Tune the silence timeout (default 10s) and how many checks to allow (default 2). The counter is monotonic by default, so background noise can't keep an abandoned call alive forever.
Maximum call length
Off by default. Set a hard ceiling — 30 seconds to 4 hours — measured from the moment the call is answered. When reached, the agent says a brief goodbye and hangs up regardless of conversation state. It's a graceful ceiling: a goodbye queued behind an in-progress sentence waits for that sentence to finish.
Use both together for full protection against stuck calls. See the Call Lifetime docs.
