What it is
Meta’s WhatsApp Business Calling API brings Voice over IP calling to the WhatsApp Business Platform (WhatsApp API). Available in most countries where the platform is supported, it lets you chat, call and scale — without leaving the conversation.
Unifunl supports it natively: your team and your AI agent work from one inbox where every call sits next to the messages that led to it.
Enable it instantly with a toggle
Switch calling on for your WhatsApp number from Unifunl. No setup fees, no extra hardware, nothing to install.
Calls, chats and your AI in one place
Calls run alongside your AI agent, automations and store data — the same customer profile, orders and history.
Switch between call and chat without losing context
Every call is logged in the conversation. Send a product, a price or a payment link while you’re still on the line.
Credibility built in
Calls come from your WhatsApp Business profile — name, logo and green tick — so customers know exactly who’s calling.
Pricing & permissions
Here’s how WhatsApp calling works and what it costs — the rules are set by Meta and designed to keep calls welcome.
Business-initiated calls
You must request permission during an active conversation. One request is allowed every 24 hours, with a maximum of two in seven days. Once approved, the call must happen within 72 hours.
1 request / 24h · 2 / 7 days · 72h to call
Customer-initiated calls
Customers can call you directly by tapping the call icon on your profile, a call button in a message or a call link. Share them in chats, ads and on your site so they reach the right team in one tap.

What it costs
Incoming calls are completely free. Outgoing calls are billed per minute at Meta’s rate for the destination region. Unifunl charges no setup fee and adds no markup on calls.
Incoming free · outgoing per minute · 0 markup
How much it costs
Estimate your monthly calling spend: pick the region your customers are in and drag the slider. Rates are Meta’s published list rates in USD.
Outgoing call rates depend on
Call duration
Charged in six-second increments, rounded up — a 56-second call counts as 60 seconds.
The customer’s country code
Each destination region has its own rate. Tunisia, Morocco and Algeria fall under “Rest of Africa”.
Your monthly volume
The more minutes you call in a month, the lower the rate. Tiers reset at the start of every month.
No solution-provider fees
Many providers add hidden costs — setup fees, hosting charges or a markup on every minute. Unifunl doesn’t. You pay exactly what Meta charges, and nothing else.

Use cases
From ecommerce and hospitality to healthcare, real estate and education, a call can be the difference between high intent and lost interest.
Close high-value deals faster
A personal touch for the orders that matter — bundles, custom quotes, B2B baskets.
“Can you do a better price for 20 units?” → agreed on the call, order placed in the thread.
Build trust, handle objections
Hesitation dissolves faster in a voice than in a wall of messages. Reassure, explain, close.
“Is it really original?” → three minutes of voice, one order.
Resolve complex issues in real time
Returns, wrong sizes, a delivery gone sideways — sort it out in one call instead of a day of back-and-forth.
“The set arrived without the serum” → replacement confirmed live.
Confirm bookings and deliveries in seconds
Appointments, cash-on-delivery orders, time slots: a 30-second call beats a thread of unanswered messages.
“Thursday between 2 and 6 pm works?” → confirmed, courier notified.
