This OID stores an integer representing the timeout in seconds for waiting on a response to a status inquiry message; if the timer expires, the call is terminated. Engineers use status inquiries to verify that endpoints are still alive during long idle periods; this timer prevents the device from indefinitely waiting for unresponsive endpoints. Example: setting to 5 seconds means when the device sends a status check on an active call, it expects a reply within 5 seconds or will clear the call.
