Trusted by high-growth teams
How it works
Calls from the phone network come in over your usual trunk. WhatsApp calls reach the Astroline Meta Carrier Platform, are converted to SIP in real time and enter the same IVR over a second trunk.
We turn every WhatsApp call into a standard SIP session. Your platform receives it like any other inbound call.
One number receives calls from the phone network and from WhatsApp, with two trunks in parallel.
Every call reaches the right queue or agent based on your contact center logic.
IVR, recording, analytics and CRM work just as they do for every other call.
Why WhatsApp
A call from a verified business profile earns more trust than an unknown number. And there's no friction: from chat to voice in one tap.
Customers see your company's name and verification before they call or answer.
Customers go from typing to calling in one tap, without dialing a number or switching apps.
Call your customers on WhatsApp from your verified profile once they've given you permission.
Calls travel over data, so customers can reach you from any country without international prefixes.
Use your current numbers or get new DDIs for your WhatsApp Business accounts.
WhatsApp encrypts the call, and once it enters your contact center your own security policies apply.
People or AI
Your agents take WhatsApp calls in the tool they already use. After hours or at peak times, an AI voice agent answers, resolves and logs everything.
We deliver the call over SIP Trunk to the platform you already use, with your queues and your recording.
They speak naturally, capture details first time and reply without pauses.

WhatsApp Business Calling allows businesses to make and receive voice calls directly inside WhatsApp conversations. Customers can move from chat to voice with a single click, without dialing numbers or switching apps.
Astroline operates as a specialized carrier between WhatsApp and your enterprise voice stack. When a customer starts a call from WhatsApp, the communication first reaches the WhatsApp Business platform and then passes through the Astroline Meta Carrier Platform. Our platform converts that interaction into a standard SIP session and delivers it into your Contact Center through a SIP Trunk.
The Astroline Meta Carrier Platform is a carrier-grade voice infrastructure layer that connects the WhatsApp calling ecosystem with enterprise telephony systems. It acts as the bridge between WhatsApp APIs and the SIP infrastructure used by modern Contact Centers.
Contact Centers are built on SIP-based voice infrastructure, while WhatsApp calls are delivered through data APIs. Astroline handles the protocol conversion and routing required so WhatsApp calls can behave like any other inbound voice interaction inside your Contact Center.
Yes. Once the call reaches the Astroline SIP Trunk, the agent receives it as a standard inbound call in the Contact Center platform. That means you can apply IVR, agent queues, recording, analytics and CRM integration without changing your core workflows.
Yes. The same number can receive both traditional phone calls and WhatsApp voice calls. This is managed through two parallel trunks: a PSTN trunk for conventional telephony and a dedicated WhatsApp trunk connected through the Astroline Meta Carrier Platform.
The PSTN trunk receives calls from the traditional telecom network, while the WhatsApp trunk handles calls initiated from the WhatsApp application. Both trunks can route calls into the same IVR or the same agent queues inside the Contact Center.
WhatsApp provides several advantages: • Customers already use the app every day • Calls come from a verified business identity • It creates a frictionless move from chat to voice • It works globally without dialing barriers • It builds more trust than an unknown phone number
Yes. Once the call enters the Contact Center through Astroline’s SIP Trunk, you can apply standard capabilities such as call recording, AI transcription, conversation analytics and CRM logging.
Yes. WhatsApp uses end-to-end encryption to protect communications. Once the interaction enters your Contact Center infrastructure, you can apply the same security and compliance policies used for traditional voice calls.
WhatsApp Business Calling is especially valuable for Contact Centers, BPOs, customer service teams, e-commerce brands, logistics businesses and companies operating across multiple markets.
To enable the service, you need an approved WhatsApp Business Platform account and voice infrastructure connected to a carrier capable of routing these calls into the Contact Center. Astroline provides the Meta Carrier Platform, SIP connectivity and the full onboarding process.
We support you through the whole process: WhatsApp Business Platform onboarding, SIP connectivity and go-live with your contact center.
