PSTN Dial Out

Pull landlines and mobile phones from 40+ countries directly into your voice channels. No app download required for the callers — they just answer the phone.

Overview

Not everyone lives in a browser. Field teams, clients, vendors, and external stakeholders may not have whoot. installed. With Channel Dial Out, included in every whoot. plan, you can call any phone number and bridge them into your voice channel.

The caller receives a standard phone call and is immediately connected to the channel audio. They can hear everyone and speak — just like any other participant.

Step 1: Enable Dial Out

1. Navigate to your dashboard
2. Click the settings icon on the channel
3. Toggle Channel Dial Out to enabled
4. Save your changes

Dial out is included in every plan. Usage counts towards your team's pooled allowance (100 min/user/month).

Step 2: Dial a Phone Number

1. Join the channel with dial out enabled
2. Click the Dial Out button in the channel controls
3. Enter the phone number in E.164 format (e.g. +1 212 555 0123)
4. Click Call

The recipient receives a standard phone call. When they answer, they're connected to the channel immediately.
