A few clear answers

Before the
first conversation.

What is an AI phone agent and how does it work?

An AI phone agent answers and makes calls in a natural voice, follows the flow you build, and acts on what it hears. In Sysevo you build one in either a guided simple view or a full visual workflow editor with branching logic, pick the model behind it from OpenAI, Claude, Gemini or Grok, choose a voice, and give it tools and knowledge bases it can use mid-call. It handles inbound and outbound on the same platform.

Can an AI agent book appointments and take payments during a call?

Yes. An agent can book an appointment, send an email, take a payment, create a task or send a form, queued the moment the call is analysed, with your approval required on anything that reaches the caller. Bookings go into the same calendar your booking links use, so a caller at nine on a Sunday gets a real slot rather than a promised callback.

How natural does it sound, and can I use my own voice?

There are over 6,000 voices to browse by accent, age, gender and use case. You can tune personality, speaking pace and interruption sensitivity per agent. Voice cloning is available from Growth: upload a short sample and the agent speaks in that voice, whether that is a founder or a brand ambassador.

What happens on the call after it ends?

Every call is recorded, transcribed and analysed automatically, against up to 15 custom fields you define for your industry. The contact is created or updated, the caller profile gains whatever the agent learned, the deal moves to the pipeline stage the outcome implies, and any follow-up action is queued. None of that is a separate integration you have to wire up.

Do I need to change phone number or provider?

No. Rent a Sysevo number from $3 a month or forward the line you already use, with no porting paperwork either way. On Command you can bring your own carrier instead, connecting Twilio, Telnyx, Vonage, Plivo, Cloudonix or Vobiz, or self-hosting over SIP through Asterisk if you run your own telephony.

What does it cost to run a call?

Calls run at $0.14 a minute on Launch, $0.12 on Growth and $0.10 on Command, and only once your included plan minutes are used. Those minutes are one monthly pool shared by your AI agents and your reps’ power dialer, they reset each month with no roll-over of unused minutes, and calls on premium AI models use 2.5 plan minutes per minute. That rate covers the whole call and everything after it: telephony, speech to text, the model turns, the voice, then recording, transcription, analysis against your custom fields, the caller memory update and any queued follow-up action.
