I cannot enable workspace-level telephony permissions directly—that requires Retell support team access with admin privileges.

For immediate disconnection issues with Retell-provisioned numbers, check these common causes:

Verify call format:(1)

  • Ensure from_number is your valid Retell-purchased number(1)
  • Ensure to_number is in E.164 format (e.g., "+12137774445")(1)
  • Retell Telephony only supports US numbers as destinations(1)

Check API authorization:(1)

  • Verify your API key authorization is correct(1)
  • Confirm override_agent_id is valid if you’re using it(1)

Review call status:(1)

  • Check the call status and error messages in your Retell dashboard(1)

For workspace-level enablement or persistent issues, contact Retell support:

The support team can review your workspace configuration and enable any required telephony permissions that may be restricted at the account level.
