How long can an Architect call flow run?
As long as the system periodically detects caller input, for example, speech or DTMF, Architect places no limit on how long a flow can run. However, if six hours pass with no caller activity, then the flow silently disconnects. This limit is beneficial for detecting and terminating orphaned calls. Such calls are rare, but do occasionally occur.
Note: The six-hour timer resets anytime the system detects activity.
