Knowledge United

IPTT: In this Authorized Cisco course, get the knowledge and skills required to troubleshoot Enterprise CallManager, Unity, and IP network deployments. You'll begin by learning a systematic approach to troubleshooting AVVID networks and reviewing CallManager signaling protocols, and you'll continue with topics such as dial plans, E911 implementation, internal service tools, and command line interface tools. You'll cover external tools, troubleshoot gateway problems with routers and switches, and look at Call Detail Records and the administrative reporting tool. Finish up by troubleshooting voice over IP quality and Unity problems.

Superior Hands-on Labs

We offer a unique, real-world GWGK/IPTT lab environment that teaches you how to build and test a sophisticated IP telephony network that you can use as a template for a real deployment, including fault-tolerant gatekeeper (gatekeeper clusters) and directory gatekeeper deployments. You will also learn to troubleshoot a sophisticated IP telephony network based on best practice recommendations for a real deployment. We have set ourselves apart from other Cisco training providers by enhancing our GWGK/IPTT hands-on labs to include a real dial plan and Class of Service for calling out to the PSTN, branch offices, and PBXs; fault-tolerant gatekeepers; and connections from multiple CallManager clusters to multiple gateways. No other training company offers a unique real-world lab solution like ours.

Our voice network labs use the latest hardware and software.

• Troubleshoot Cisco's new ISR routers: 2811s are used throughout the network
• Gain experience with recent stable IOS release: 12.3.14T3
• Configure CallManager 4.1.3
• Explore router DSP configuration: PVDM2-32 cards in every 2811 router
• Every router has 2xFXS, 2xFXO, and 2xT1 ports (PRI and T1-CAS) as well as serial ports for WAN connectivity
• All of the latest tools are deployed on the laptops for analyzing traces
• All laptops have sniffers installed

All of our IP telephony courses provide a simulated PSTN.

• Deploy Cisco CallManager 4.1.3sr1
• Every pod has internal and external phones
• Build and test a real dial plan including:
  • 911
  • 3-digit service codes: 411, 511, etc.
  • 7-digit local numbers: 681-1901
  • 10-digit local numbers: 416-681-1901
  • 11-digit long distance numbers: 1-733-802-1901
  • International numbers: 011441902

And just like in a real network:

• The same simulated PSTN is accessible through both PRI and FXO ports
• The same simulated PSTN is accessible through all four clusters providing failover scenarios for bandwidth and connectivity problems
• Different area codes are deployed at all sites (two per cluster)

We have the best Gatekeeper labs.

• Connect your cluster to three others using fully meshed gatekeepers
• Connect your cluster to three others using a fully fault-tolerant gatekeeper cluster model based on 4.1 SRND design
• Enhance your gatekeeper deployment by deploying fault-tolerant directory gatekeepers based on 4.1 SRND design
• Add H.323 gateways to the deployment in a challenge lab
• Test calls between PBXs using gatekeeper-controlled routing

MGCP is deployed at HQ and H.323 at the branch.

• Both HQ and Branch "Arouters have PRI and 2xFXO port connections to simulated PSTN
• Deploy and test a complete dial plan for both protocols including failover from PRI to FXO ports for 911
• Configure a comprehensive and testable dial plan including over 50 dial peers on H.323 router. This is a configuration you can take with you to use at your organization!
• Deploy and test SRST on an MGCP-controlled router with supporting dial peers and Class of Restrictions (COR) to maintain routing and Class of Service in case of CCM failure
• Deploy and test SRST on both H.323- and MGCP-controlled routers with COR to maintain Class of Service in case of CCM failure
• Deploy and test COR on both routers

Configure connections to simulated PBXs via T1-CAS using MGCP at HQ and H.323 at Branch A.

• 2 PBXs connected via multiplexer
• Configure DSO-groups connecting to 2 different PBXs
• Test calls from PBX to 911, service codes, local, long distance, and international numbers, and test calls between PBXs using gatekeeper-controlled routing

You will troubleshoot a network with the following features:

• Four CallManager clusters deployed: two students are responsible for each cluster
• Each cluster has a Headquarters (HQ) and Branch router in different area codes
• The Headquarters router is MGCP-controlled
• The Branch router is H.323-controlled
• Both HQ and Branch have 2 PBXs attached via T1-CAS
• Clusters are connected via gatekeeper controlled ICTs
• Gatekeeper clusters and fault-tolerant directory gatekeepers are deployed
• SRST is fully deployed on all routers
• COR is fully deployed on all routers
• Hardware and software resources are deployed for conferencing
• Transcoding resources are deployed

Mini Camp Hours

Class begins each day at 8:00 AM and may extend until 8:00 PM.
Note: Students should expect class to run late into the evening on most days. In a typical Mini Camp, it is not uncommon for some students to remain past 8:00 PM depending upon the class size and experience of the students.

Exam Vouchers Included with the Mini Camp:

• (1) 642-452 GWGK
• (1) 642-425 IPTT

Who Needs to Attend

Network engineers responsible for implementing Cisco Voice Gateways and Gatekeepers in Enterprise or Service Provider environments and for IP telephony troubleshooting would benefit.

This course is recommended for technical professionals pursuing CCVP certification or the Cisco IP Telephony Operations Specialist certification.
