Cisco Certified Network Professional (CCNP®) Voice validates advance knowledge and skills required to integrate into underlying network architectures. Furthermore, this certification validates a robust set of skills in implementing, operating, configuring, and troubleshooting a converged IP network. With a CCNP Voice certification, a network professional can create a collaboration solution that is transparent, scalable, and manageable. The CCNP Voice focuses on Cisco Unified Communications Manager (formerly Unified CallManager), quality of service (QoS), gateways, gatekeepers, IP phones, voice applications, and utilities on Cisco routers and Cisco Catalyst switches.
CCNA Voice or any CCIE Certification can act as a pre-requisite.
