Blocked Call List API Guide

Feature Overview

The Global Block Call Table (Setup Guide) can be managed via the REST API. This allows you to create, update, delete, and list and query blocked numbers. This is useful for integrating with other systems, or for bulk management of the block list.

Customers have used this API to scrape and import numbers from other systems, or to integrate with their own internal systems for managing blocked numbers.

Feature Requirements

• Call Telemetry Appliance 0.8.0 or higher
• Call Telemetry Advanced (opens new window) License
• Cisco Callmanager 8.5 with CURRI API Integration to Call Telemetry

Postman API Documentation and Collection

The API is fully documented with Postman, and includes examples of how to submit and manage blocked numbers.

You can also fork the Postman collection to your own Postman account.

You can find the Postman Collection here:
