Voice & Video Calling

Answer every customer call from your desktop

Take and place WhatsApp and Messenger calls, Messenger video calls and regular phone calls through Twilio or Telnyx — right inside the conversation.

WhatsApp & Messenger calls

Built on Meta’s official Calling APIs — ring, answer and call back without touching a phone.

Messenger video

Turn video on mid-call and expand it to a large view when you need to see the customer.

Phone numbers too

Connect Twilio or Telnyx to handle regular phone calls in the same app.

Call the right way

Ask customers for permission to call, respect their choice, and only ring when you’re open.

How it works

How voice & video calling works

Ask permission

Send a one-tap call permission request in the chat, as Meta requires for business-initiated calls.

Ring the team

Incoming calls ring on every available teammate’s desktop. First to answer takes it.

Talk

Mute, keypad, Messenger video and a floating call pill while you look things up.

Log

Answered, missed or declined — every call is filed in the thread with who handled it.

Frequently asked questions

Is WhatsApp calling free?

Meta charges for some business-initiated WhatsApp calls according to its own pricing. Those charges are billed by Meta, not by ThreadWave.

Do customers need to install anything?

No. Customers answer in their normal WhatsApp or Messenger app.
