​
Automatic SIP Trunk Setup

When you create a Twilio provider, the following resources are automatically configured:
  1. SIP Trunk: A new trunk is created in your Twilio account with termination URI
  2. Credential List: A credential list is created and attached to the trunk
  3. SIP Credentials: Username/password credentials are generated for call authentication
  4. Local Records: Provider and SIP credentials are stored securely in your organization

​
Credential Requirements

Your Twilio credentials must have the following permissions:
  • Read access to account information
  • Create/manage SIP trunking resources
  • Create/manage credential lists
  • Read incoming phone numbers

​
Security

  • Auth Token is encrypted before storage
  • Account SID is stored as plain text (it’s a non-sensitive identifier)
  • Auth Token is never exposed in API responses
  • SIP passwords are randomly generated (32 characters)

​
After Creation

Once the provider is created:
  1. Use the /available-numbers endpoint to see phone numbers in your Twilio account
  2. Import desired phone numbers using the /import-numbers endpoint
  3. Link imported phone numbers to agents for call handling
