Important for US Numbers: Register for A2P 10DLC

​
Register

  1. Go to Twilio’s A2P 10DLC registration page: Twilio A2P 10DLC Registration Guide
  2. Complete brand and campaign registration to comply with US carrier regulations.
  3. Wait for approval (can take a few days).
  4. Once approved, messages will send successfully.
Troubleshooting: If your messages fail to send, check the Twilio logs for these error codes:

​
Add SMS templates

Once connected, follow these steps to create SMS templates:
  1. Click Add SMS in the SMS Messaging section.
  2. Fill in the form:
    • Title: A descriptive name for the SMS template (e.g., “reservation_confirmation”).
    • SMS Body: The content of the message. Ensure it is clear and concise.
    • Phone Number: Choose the Twilio phone number associated with this message.
  3. Save the template to make it available during conversations.

​
Managing templates

All created SMS templates are listed in the SMS Messaging section. You can:
  • Edit: Modify the title, message content, or associated phone number.
  • Duplicate: Quickly create a copy of an existing template for similar use cases.
  • Delete: Remove unused or outdated templates.

​
Using an SMS template

  1. Go to the knowledge base build page
    • Ensure you are on the knowledge base builder page.
  2. Add an action to a knowledge base card
  3. Set SMS action
    • Prompt something like “If someone asks for more details, send” in the action box.
    • Click the + button on the right-hand side of the box and choose SMS > {SMS template title created}.
    Here’s an example of how to construct a prompt for your voice agent to send an SMS: 
    After the caller confirms that they would like to receive an SMS message with further details, call {{SMS_template}} to send the SMS out.
  4. Click ‘Save’ and ‘Publish’

​
Best practices

  • Clarity: Keep SMS messages brief and directly relevant to the user’s needs.
  • Personalization: Use variables or dynamic fields (e.g., username or account details) to enhance engagement.
  • Compliance: Follow SMS regulations, including providing opt-out options when necessary.

​
Example: Integrating call handoffs with SMS

Combine Call handoff functionality with SMS to streamline user interactions:
  1. The agent routes a call to a specific agent or team using Call Handoffs.
  2. At the same time, an SMS template is triggered, sending the caller additional details or confirmation of the transfer.

​
Integrating SMS into a function

SMS can be triggered as part of a function using the conv objects:
  • conv.send_sms
  • conv.send_sms_template 
    conv.send_sms("+15551234567", "Your request has been processed.")
