Questions
Synthflow management — common questions
What does interruption sensitivity mean in Synthflow?
It is the number of words a caller must speak before the agent stops and listens. Lower values make the agent yield quickly; higher values let it finish longer phrases. Setting it to Off disables interruptions.
What is human detection on Synthflow warm transfers?
On a warm transfer, human detection waits for a live person to answer before delivering the briefing, so it is not played to a voicemail or phone menu. The wait can be set from 30 seconds to 30 minutes.
Should we switch interruptions off in Synthflow?
Not for live callers. An agent that cannot be interrupted talks through people trying to correct it; a tuned word count works better.
How much does Synthflow management cost?
From $100 a month. The exact price depends on users, volume and what needs setting up, and you get it in writing within 2 working days, without giving us access.
Is there a minimum term?
No. It is month to month with 30 days’ notice.
