TwiML App Setup for Browser Phone

+
+

Auto-Configuration (Recommended)

+

Let the plugin automatically set up everything for you:

+
+
+ + +
+ +
+

Select Phone Numbers to Configure:

+
+

Loading phone numbers...

+
+
+ + +
+
+ +
+ +

Routes calls based on agent preferences (browser vs cell phone)

+
+

+ Full Setup: Create TwiML App, set webhooks, configure selected phone numbers.
+ Numbers Only: Configure selected phone numbers with smart routing (requires TwiML App already set up). +

+
+
+ +
+ +

Manual Setup Instructions

+

Or follow these steps to set up manually in your Twilio Console:

+ +
+
+

1. Create TwiML Application

+
    +
  1. Go to Twilio Console → Voice → TwiML Apps
    2. +
  2. Click "Create new TwiML App"
    3. +
  3. Enter a friendly name: Browser Phone App
    4. +
  4. Set Voice URL to: + +
    5. +
  5. Set HTTP Method to: POST
    6. +
  6. Leave Status Callback URL empty (optional)
    7. +
  7. Click "Save"
    8. +
+
+ +
+

2. Get TwiML App SID

+
    +
  1. After creating the app, copy the App SID (starts with AP...)
    2. +
  2. Paste it in the "TwiML App SID" field above
    3. +
  3. Click "Save Changes"
    4. +
+
+ +
+

3. Test Browser Phone

+
    +
  1. Go to Twilio WP Plugin → Browser Phone
    2. +
  2. Wait for status to show "Ready"
    3. +
  3. Enter a phone number and select caller ID
    4. +
  4. Click "Call" to test outbound calling
    5. +
+
+
+ +
+
