Troubleshooting Cisco Unified Communications Systems (TUC) v1.0 equips network professionals with the knowledge and skills required to troubleshoot Unified Communications Systems / solutions in Enterprise, Mid-Market, and Commercial deployments. TUC teaches troubleshooting methodology, triage, resources, tools and fixes at the integrated System / Solution level, and for components (such as Cisco Unified Call Manager, Cisco Unity, videoconferencing, and infrastructure).
Our TUC Lab environment consists of four interconnected CallManager (CCM 5.0.4) clusters. Two students are responsible for troubleshooting each cluster. Each cluster contains two 2811 Integrated Services Routers running IOS 12.4.9T2 representing a Headquarters and Branch site. A sophisticated telephony simulation is provided allowing you to troubleshoot PRI and FXO connections to the PSTN, T1-CAS DS0-Groups to a channel bank connected to two PBXs, and FXS ports connected to analog phones. Each 2811 router is provisioned with a PVDM2-32 providing DSP resources and a serial card for WAN connectivity.
A complete CallManager deployment is preconfigured on a cluster at the Headquarters site with one Publisher and one Subscriber:
- A full dial-plan including Class of Service with blocking on lines
- IP Phone and line configurations
- Locations and regions
- Device pools
- Media resources, resource groups, and resource group lists
The Headquarters and Branch A routers have a base IP configuration providing network connectivity.
All laptops have the following tools loaded:
- VNC and terminal services
- Q931 enhanced translator
- Triple combo parser
- translatorX
- Cisco trace collection tool
- Cisco Voice Log Translator
- Ethereal
We offer more than 50 possible trouble tickets that instructors can apply at their discretion during class with additional trouble tickets are constantly being added to the labs.
Lab 1: Trouble Tickets - Phone Registration
A variety of phone registration problems can be inserted into the network concerning:
- Auto-registration
- Microsoft DHCP
- Router DHCP
- Helper address
- Routing
- DNS
- Access lists
Lab 2: Trouble Tickets - Dial Plan

Common Partitions
A variety of dial plan problems can be inserted into the network concerning:
- Misconfigured route patterns
- Route patterns with wrong partitions
- Misconfigured route filters
- Problems with the "@" wildcard
- Wrong calling search space on lines and phones
- Incorrectly configured calling search spaces
- Misconfigured call forward calling search spaces
- Wrong calling search spaces on gateways
- Route lists misconfigured
- Bad translation patterns
- One-way audio
- Digit manipulation
Lab 3: Trouble Tickets - MGCP Gateway
A variety of MGCP gateway problems can be inserted into the network concerning:
- MGCP domain names
- Configuration of expected and significant digits
- FXS ground vs. loop start
- Attendant numbers
- T1-CAS Digit Sending
- FXO port configuration
- Service provider problem: wrong DID sent
- Service provider problem: PRI not up
Lab 4: Trouble Tickets - H.323 Gateway
A variety of H.323 gateway problems can be inserted into the network concerning:
- H.323 source addresses
- Bogus dial peers
- Bad or missing translation-profiles for DID
- Second dial tone on incoming calls from PRI
- Bad incoming calling search space
- Misconfigured dial peers
Lab 5: Trouble Tickets - Locations and Regions
Each cluster is configured for bandwidth management allowing a variety of codec and bandwidth-related problems to be explored:
- Misconfigured locations
- Devices in wrong locations
- Misconfigured regions
Lab 6: Trouble Tickets - SIP
A variety of SIP problems will be inserted into the network concerning:
- Third-party SIP device configuration

- Presence group issues
- Presence configuration across SIP trunks
Lab 8: Additional problems to troubleshoot:
Intercluster trunks are configured between the cluster with redundant gatekeepers (using gatekeeper clusters) and a directory gatekeeper deployed. Extension mobility is deployed in the network as well as numerous features such as Call Park, Music on Hold, and Conferencing using software and DSP resources.
We offer a unique, real-world TUC lab environment that teaches you how 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 TUC hands-on labs to include a real dial plan, the latest recommendations for Class of Service (CoS) for calling out to the PSTN, branch offices, and PBXs, and fault-tolerant gatekeeper and directory gatekeeper deployments. 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.x and 5.x
- 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.x and 5.x
- 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)
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 two 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
