This nugget focuses around troubleshooting call routing failures in a single-site, single-cluster environment. Topics focus around CCM digit analysis, partitions and calling search spaces, translation patterns, and more.
Video 13: CCM Troubleshooting: Call Failures, Part 2|33:25
The call failure troubleshooting discussion moves to calls outside your cluster. In this nugget, Jeremy focuses on MGCP and H.323 gateway concepts and troubleshooting steps.
Video 14: CCM Troubleshooting: Call Failures, Part 3|43:27
In this final call troubleshooting nugget, you will focus on CallManager-specific troubleshooting areas. These include troubleshooting caller-id, secondary dial-tone, one-way audio, dead air, and ringback.
Video 15: CCM Troubleshooting: Call Routing|24:32
Just like data packets, correct routing of voice calls is essential. This nugget highlights major troubleshooting areas for CCM call routing including TEHO issues, call disconnects, and proper data to PSTN network fallback.
Video 16: CCM Troubleshooting: Gatekeeper Communication|37:28
H.323 Gatekeepers have the ability to simplify the network configuration and management for your VoIP environment. In this nugget, Jeremy discusses the concepts behind H.323 Gatekeepers, Gatekeeper configurations, and the troubleshooting process.
Video 17: Network Troubleshooting: Voice Quality Issues|48:58
Quality of Service (QoS) issues can quickly destroy a VoIP network. This nugget is dedicated to looking through key QoS requirements and configurations, along with QoS troubleshooting methods.
Video 18: Cisco Unity: Integration Issues|47:39
The Cisco Unity voicemail system is really the "black sheep" of the CCVP certification track since Cisco did not include any exams tailored to the Unity system. In this nugget, Jeremy goes beyond basic Unity troubleshooting to explore foundation Unity – CallManager integration, then walks through common Unity troubleshooting topics: Message Waiting Indicators (MWIs), Call Transfer issues, and Unity Subscriber settings.
