Frequently asked questions
What happens when a TopCalls AI agent reaches voicemail?
TopCalls agents detect answering machines automatically. Depending on your campaign settings, the agent leaves a short personalized voicemail or hangs up and schedules a retry for later in the day. Voicemail detection keeps your $0.35/min spend focused on live conversations instead of recorded greetings.
How fast do TopCalls AI agents respond in conversation?
TopCalls agents respond with sub-500ms response latency, which is close to the natural pause in human conversation. Prospects can interrupt mid-sentence and the agent stops, listens, and adjusts its answer, so calls feel like a dialogue instead of a recording playing at them.
Do AI voice agents work for outbound sales calls?
Yes. TopCalls runs outbound qualification, appointment setting, follow-up, and win-back campaigns, with TCPA, TSR, DNC, and GDPR compliance tooling built in. The agent works from your script, adapts to each prospect's answers, and hands hot leads to your sales team while they are still on the line.
