CSCGW - Cisco SIP, CUBEs and Gateways

• VoIP, components of a VoIP network, VoIP protocols, special requirements for VoIP calls, and Codecs
• Configure gateway interconnections to support VoIP and PSTN calls
• Basic signaling protocols used on voice gateways
• Configure a gateway to support calls using different call control and signaling protocols
• Define a dial plan, describing the purpose of each dial plan component, and implement a dial plan on a voice gateway
• Implement a Cisco Unified Border Element (CUBE) gateway to connect to an Internet Telephony Service Provider
• Investigate the use of various traditional telephony connections, such as FXS, FXO, E&M, T1 (CAS and PRI), and E1 (CAS and PRI)
• Configure and troubleshoot Cisco's new ISR routers and explore their DSP configuration (PVDM3 cards)
• Configure H.323 gateways and review their functions and operation
• Configure Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP)
• Experience G.711, and G.729 voice coding schemes
• Configure Call Admission Control three different ways
• Configure proper Caller ID
• Experience real-world connections to PBXs, and the PSTN
• Configure your router/gateway equipment to connect to our public dial plan network using different call control protocols and procedures

You'll gain an understanding of converged voice and data networks as it relates to gateway design and deployment. You will gain comprehensive hands-on experience configuring and deploying Gateways, CUBEs, Quality of Service, and troubleshooting in VoIP networks.

In addition to the knowledge and skills required to integrate gateways into an enterprise VoIP network, you'll learn how to build and test sophisticated IP telephony dial plans that use both CUCM Dial Plan and Dial Peers at an IOS level which can be used as a template for a real deployment.

The course includes a comprehensive study of Quality of Service (QoS), in which you'll learn to configure QoS to support real-time traffic.

• Only course dedicated to specific Gateway technologies and Quality of Service
• World-Class Certified Cisco Systems Instructors

Why Take CSCGW from Learn Quest?
Every pod has internal and external phones, and just like in a real network, the same simulated public switched telephone network (PSTN) is accessible through all clusters providing failover scenarios for bandwidth and connectivity problems. To more accurately reflect real-world scenarios, you will configure the gateway connections to simulated PBX systems.

We have set ourselves apart from other Cisco training providers by enhancing our CSCGW hands-on labs to include a real dial plan and Class of Service for calling out to the PSTN. Our voice network labs use the latest hardware and software so you will gain experience with the recent stable IOS release (15.X IOS M currently). Plus, each pod contains the following gateway cards for student configuration: 2xFXS, 2xFXO, and 2xT1 ports (PRI and T1-CAS) as well as serial ports for WAN connectivity. All of our IP telephony courses provide a realistic simulated PSTN accessible through both PRI and FXO ports. You will build and test a real dial plan including:

• 911
• three-digit service codes: 411, 511, and so forth
• seven-digit local numbers
• 10-digit local numbers
• 11-digit long distance numbers
• International numbers
• Configure and test all dial peers as appropriate

Network engineers, architects, and support staff who:
