CCNP Voice

The Cisco Certified Network Professional Voice (CCNP® Voice) certification is a "professional" level certification in Cisco's certification pyramid.  It confirms the skills required to implement, operate, and troubleshoot voice solutions with the underlying network architecture.

The Cisco CCNA Voice certification must first be obtained before the CCNP Voice can be achieved (unless you already possess a CCIE certification). 

CCNP Voice Prerequisites
