Why Global Knowledge?

The Global Knowledge lab environment has been customized for North American students to ensure that CCNP Voice Professionals learn the skills they need for the North American environment. Other training partners provide a basic topology oriented with a HQ in Europe and a branch in North America. Our expert instructors designed an enhanced topology that's better for understanding the issues with multisite deployment and globalization in North America and the nuances of implementing the NANP (e.g., 10-digit dialing, service codes beyond 911, issues with local and long distance calls to the same area code, overlapping 7- and 10-digit dialing, etc.).
