Get the dialer running and place your first outbound call. The whole process takes about five minutes if you already have a Twilio account.

​
Prerequisites

Before using the dialer, you need:
A Twilio account with at least one provisioned phone number
Twilio credentials added to Consuelo (Account SID, Auth Token, API Key, API Secret)
A browser with microphone access (Chrome works best)
New to Twilio? Follow our Set Up Twilio guide first. It walks you through creating an account, buying a number, and connecting it to Consuelo.

​
Step 1: Configure Twilio

  1. Go to Settings → Integrations → Twilio
  2. Enter your Twilio credentials:
    • Account SID — from your Twilio console dashboard
    • Auth Token — from your Twilio console dashboard
    • API Key SID — create one under Account → API Keys
    • API Secret — shown once when you create the API Key
  3. Click Save
Copy the API Secret immediately. Twilio only shows it once. If you lose it, you’ll need to create a new API Key.

​
Step 2: Add a Phone Number

  1. Go to Settings → Integrations → Twilio → Phone Numbers
  2. Your Twilio numbers should appear automatically
  3. Select a primary number — this is the default caller ID for outbound calls
No numbers showing up? Make sure you’ve purchased at least one phone number in your Twilio console. Numbers must have voice capability enabled.

​
Step 3: Allow Microphone Access

When you open the dialer for the first time, your browser will ask for microphone permission.
  1. Click Allow when prompted
  2. If you accidentally denied it, click the lock icon in your browser’s address bar → Site settings → set Microphone to Allow

​
Step 4: Make Your First Call

  1. Open the dialer from the sidebar or press the dialer shortcut
  2. You’ll see the home screen with a dial pad and call setup options
  3. Type a phone number or search for a contact
  4. Click the green call button or press Enter
  5. You’re connected!
During the call, you’ll see controls for:
  • Mute — silence your microphone
  • Hold — place the caller on hold with music
  • Keypad — send DTMF tones (for navigating phone menus)
  • Transfer — hand the call to someone else
  • End — hang up

​
What’s Next?

Now that you’ve made your first call, explore what else the dialer can do:

Run a Queue Campaign

Load a contact list and work through it systematically.

Try Parallel Dialing

Call multiple people at once to save time.

Set Up Local Presence

Match your caller ID to the recipient’s area code.

Configure Caller IDs

Manage multiple phone numbers for different use cases.
