AI phone calls over WhatsApp and phone: how a digital executive calls your customers

AI phone calls are no longer a recording that says "press 1". With Roma AI, a digital executive calls your customers and answers their calls over WhatsApp and by regular phone, to any country in the world. It speaks naturally, understands the replies, acts in your systems and logs everything. It can run many calls in parallel, follow up on WhatsApp or email and, when needed, hand the call to someone on your team with full context, because your human executives call from the same platform too. Here is how it works and which rules to set.

What an AI voice agent is (and is not)

An AI voice agent, or AI calling agent, talks over the phone or WhatsApp the way a person on your team would: it listens, understands intent, answers and asks questions. It does not follow a fixed option tree or play recorded messages. It is not an IVR menu, not an auto-dialer with a recorded message, and not a voice chatbot that answers FAQs and then forgets.

A digital executive that calls has a role (sales, selling to your base, collections or after-sales), goals, and access to your systems. The call is one tool inside a broader job. We explain that difference in what digital executives are.

AI calls over WhatsApp and over the phone

With Roma AI, the same digital executive can call two ways:

• WhatsApp calls, through WhatsApp Business, inside the channel where many customers already talk to your company.
• Regular phone calls, to mobiles and landlines.

Both work for inbound and outbound, and both reach any country. Whether you sell in Chile, Uruguay, Mexico or beyond Latin America, the executive calls each customer in their language and within the hours you set for their time zone.

WhatsApp calls vs phone calls: when each fits

	AI WhatsApp call	AI phone call
Best when	The customer is already chatting with you on WhatsApp	The contact has no WhatsApp or you only have a landline
Context	The call sits in the same chat as the messages	Linked to the customer's history in your CRM
Recognition	The customer sees your business name and profile	Depends on them recognizing the number
Typical uses	Following up a chat, collections with a payment link, after-sales	Form leads, prospecting lists, companies with landlines
After the call	Continues in chat without switching apps	Continues on WhatsApp or email

It is not a permanent choice: the executive can use whichever fits each customer and switch according to your rules. If a phone call goes unanswered, it can message on WhatsApp and offer a call there.

How automated AI calls work

1. Before the call — context. It reviews who the person is, previous contacts and the goal; for prospects it researches the person and company, for customers it checks your CRM or ERP.
2. During the call — conversation. It speaks naturally, handles objections within your limits and adapts when the person interrupts or changes topic.
3. At the close — action. A booked meeting, a payment commitment with date and amount, a logged sale or an open case, all inside your systems.
4. After — log and follow-up. Transcript, time and outcome are saved, and it sends the payment link, meeting confirmation or quote on WhatsApp or email.

Inbound AI calls and outbound AI calls

Inbound: an AI that answers calls

With inbound AI calls, callers are answered without hold time, at any hour, and helped with data from your systems: a balance, an order status, a product question, a booking. If the case needs a person, the call is transferred to your team.

Outbound: an AI that makes calls

Outbound AI calls are where the gap with a traditional team is widest: the executive can reach many people in parallel, so a campaign covers the whole list instead of the first few names. Unanswered calls are retried at another time or on another channel, per your rules.

AI call center: a virtual call center inside your team

Many companies look for an AI call center or a virtual call center to answer and call without adding seats. A team of digital executives does that job, but it is not an outsourced queue: it is part of your operation, connected to your CRM and following your rules.

	Traditional call center	AI contact center
Capacity	Limited by seats and shifts	Many calls in parallel, at any hour
Channels	Mostly phone	WhatsApp, phone, email and chat in one conversation
Records	Manual notes or raw recordings	Transcript, summary and outcome in your CRM
Actions	Noted for someone else to do	Books, logs commitments and sends links on the spot
Complex cases	Escalated to a supervisor	Warm transfer to your team with full context
Rules	Depend on each agent's training	Applied the same way on every call

It does not remove people: it takes them off repetitive work so they handle what needs judgment.

Digital and human executives on the same call

In Roma AI, calls are not only made by AI. Your human executives also call from the same platform, over WhatsApp and by phone, to any country. That enables handoff with context:

• The digital executive hands off to a person when the customer asks, when an approval is needed, or when you decide a type of case belongs to your team.
• The person continues the call, or picks it up on the next call or chat, with the summary, full history and what was already agreed. The customer repeats nothing.
• The person can hand it back so the digital executive handles the follow-up: sending the confirmation, reminding about a commitment, calling again on the agreed date.

Warm transfer to a human

A warm transfer to a human is usually where automated systems fail: the customer ends up explaining everything again. Not here, because the person sees the transcript, summary and agreements on the same platform before saying a word.

Everything stays in one history, no matter who spoke or on which channel. AI prepares, your team closes.

What AI calls do in each area

Area	Digital executive	Why it calls
Sales (SDR)	Romina	Calls new leads within minutes, qualifies and books meetings
Commercial	Diego	Offers renewals and add-ons, reactivates customers
Collections	Valentina	Reminds due dates, collects overdue debt, logs commitments
After-sales	Martín	Follows up after delivery, runs surveys, reminds maintenance

Each has its own guide: AI SDR, AI cross-selling, AI debt collection and AI after-sales. In prospecting, the figure we measured is Romina's: 86 meetings booked in her first month, combining calls, WhatsApp and email.

Rules: contact hours, do-not-contact and limits

Before launching a campaign you define contact hours by time zone (mainly for cold outreach; someone who asks to be called or fills in a form can be called right away), do-not-contact lists (honored and logged if someone asks mid-conversation), follow-up frequency and when to switch channels, what may be offered and which data is never shared, and what needs human approval. Check each country's rules on commercial communications and data protection; the executive's rules are how you apply them on every call.

Transcripts and audit for every call

Every call, over WhatsApp or by phone, by a digital executive or a person, is transcribed and linked to the customer. That lets you audit any conversation, spot frequent objections and measure contact rate, meetings, commitments or sales per campaign. Anyone on your team can take control of a conversation at any time.

Getting started

Pick the highest-volume case, decide whether to call over WhatsApp, phone or both, connect your CRM, calendar or ERP, and define the rules and which cases go to your team. Meet the whole team at ejecutivos digitales (Spanish).
