Goals and Methods The most important goal of this book is to help define a methodology and framework of collecting, analyzing, and correlating VoIP performance data from various network elements.

When correlated in a meaningful way, this data can help network operators identify problematic trends in their VoIP networks, and isolate and fix problems before they become service impacting. One key methodology in this book is to use a layered approach when troubleshooting VoIP network problems.

This helps narrow the scope of the problem in an efficient manner and also helps find the root cause. By quickly identifying the root cause of the problem, the network operator can resolve issues in a timely manner and minimize customer impact.

This book also provides guidelines for optimizing VoIP networks by defining the following: What VoIP performance data should be collected from various network elements? How to collect VOIP performance data? How to use dashboards to analyze and correlate VoIP metrics? How to use the VoIP dashboard for trend analysis and capacity planning?

This book also helps network operators troubleshoot VoIP-related issues efficiently and identify root causes to fix problems in a timely manner. However, it does not focus on traces, logs, and debug messages but rather on analyzing trends and correlating network issues to address core issues.

Troubleshooting Cisco IP Telephony. Clemm, Alexander. Network Management Fundamentals. How This Book Is Organized This book discusses some of the challenges faced by service providers and enterprise customers in deploying, managing, and optimizing VoIP in their networks.

It provides guidance on how to address voice quality issues and proactively monitor key performance indicators KPI to help gauge the health of the VoIP network. The first part of the book provides an overview of VoIP and key network management concepts. It also discusses a metrics-based approach of managing and optimizing VoIP networks. The second part of the book concentrates on different VoIP deployment models in SP and enterprise networks, and reviews the common VoIP-related problems in each deployment approach.

Note The first and second parts of the book set the stage for how VoIP is deployed in enterprise and SP networks and discusses the challenges associated with such deployments. You might feel that both these parts of the book are brief and high-level; they do not cover in-depth technology and protocol details.

This is by design; it is assumed that you already understand these basics as this information has already been covered in various other texts.

The main focus of this book is on managing and optimizing VoIP networks; these concepts are covered in detail in the third part of the book. That is why chapters in the third part of the book are longer and more detailed than the chapters in the first and second parts of the book.

This part of the book also talks about what tools can be used by customers in gauging the health of their VoIP network and improve network performance. Using performance counters, Call Detail Records CDR , and Call Agent trace logs, customers can utilize realtime data to gauge the health of their voice network and make capacity-planning decisions before network resources get congested.

These providers own the last-mile connection to end users; they use their infrastructure to not only provide Internet connectivity but also to offer VoIP services using the same infrastructure. In such deployment models, the company providing VoIP services might not own the entire network infrastructure, such as the last-mile connection to the end users, which is used for deploying this service.

They might use infrastructure, owned by other entities, to provide VoIP as an overlay service by deploying some of their own network components that are required for offering the VoIP service. This deployment model is different from the models discussed in Chapter 3. Chapter 5, VoIP Deployment Models in Enterprise Networks: This chapter explains various deployment models that are commonly used in typical enterprise networks, including the fundamental models: central call processing and distributed call processing.

It also discusses large-campus deployment schemes. It also presents a brief overview of IP Contact Centers, which are essentially an extended functionality of a Unified Communications solution.

Chapter 6, Managing VoIP Networks: This chapter discusses the best practices for planning media deployment over IP networks starting from how to assess the readiness of the network, traffic engineering, high availability, and managing the IP network and its integrated components that process voice and other media transmissions.

This chapter also covers the monitoring mechanism available to network administrators and their scope and effectiveness in managing VoIP networks. Chapter 7, Performance Analysis and Fault Isolation: This chapter discusses an approach for proactive monitoring of the VoIP network for performance analysis and fault isolation of problems caused by anomalies in the network.

It starts with explaining the VoIP network monitoring aspects including collection, categorization, and correlation of performance counters for both enterprise and service provider networks. It also discusses different ways of gauging the performance of a large-scale VoIP network by looking at various key performance indicators KPIs. This trend analysis can help network operators not only establish a baseline but also help with resource optimization and capacity planning by looking at problematic trends in the network, such as resource overutilization and changes in traffic patterns.

This chapter focuses on describing a use case in which the VoIP infrastructure and the transport and the access are managed by an SP. Different network components and their functions are described to illustrate how various call functions are implemented to provide voice services to residential and business customers.

Figure depicts a block architecture of the SP scenarios discussed in this chapter. Here, the service provider also owns the last-mile network access. Later chapters cover scenarios where the SP does not own the access network. You learn about the common VoIP networks and the corresponding components. Siddiqui, Talal, III.

The first stage is planning, which includes forming a team, defining the scope of deployment, requirements validation, and assessment of the IP network to determine whether the infrastructure is adequate to support media traffic.

The design phase includes comprehensive design-based traffic engineering and validated requirements. It not only covers call-processing servers, remote gateways, and features implementation but also covers changes to the IP network in the form of quality of service design and provisions for network resiliency. It is followed by the implementation phase, which is governed by project management principles and ensures that best practices for deployment are followed for on-time completion.

Implementation also includes a test plan execution and transfer of information to network operations prior to commissioning. The correct execution of these phases ensures minimum problems and decreases the total cost of deployment. Implementation is followed by the operations phase, with continuous optimization to close the loop. This book briefly mentions planning, design, and implementation stages and emphasizes the operations and optimization phases.

First, the hand-off to operations needs to be complete, including remediation of any issues discovered when the postdeployment test plan was executed. All the deployed devices must be discovered by the network management systems. But most important, VoIP can no longer be managed in a silo that is separate from the data network management subteam.

This book emphasizes correlating network problems with VoIP-related key performance indicators for faster problem resolution by isolating it and fixing the root cause. Operational data provides critical feedback for continuous optimization of the network, including its performance and capacity.

Optimization is not limited to fine-tuning the traffic engineering process for future growth but also for extending VoIP for the next evolution to collaboration-enabled business transformation.
