CISCO - CCNP Voice

Cisco Certified Network Professional-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 help create a telephony solution that is transparent, scalable, and manageable. The CCNP Voice  curriculum 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

Prerequisites: Students are expected to have a CCNA Voice-level of knowledge.
