|Webinar: Tips for Optimizing Your VoIP Application Quality of Experience |
The transition from analog telephony to VoIP is unlike any upgrade you've ever performed. A VoIP deployment is a major initiative that demands optimal network performance to ensure an acceptable quality of experience for end users. There are many reasons why VoIP is so demanding. Unlike most data applications, VoIP is sensitive to latency, jitter, and packet loss. However, few VoIP applications offer integrated management tools - the metrics and visibility required to deliver a superior VoIP quality of experience while ensuring network performance. The introduction of VoIP applications on your enterprise network presents specific challenges that can best be addressed with network-centric performance monitoring products.
Join NetQoS experts to learn how VoIP applications have evolved and why they demand optimal network performance. Find out how to take a performance-first approach to the network, and learn why this approach, based on deep insight into end-user quality of experience, will help you ensure optimal call quality.
Attendees will walk away from this event with an understanding of:
- How to obtain metrics on call signaling/setup protocols
- The keys to gauging the quality of voice calls
- How to measure response times to show the impact of VoIP on existing applications and vice versa
- The importance of determining the volume of VoIP traffic across the WAN - including who is using it and when - to ensure adequate bandwidth for VoIP traffic and other business-critical applications
- The value of performing active VoIP testing/monitoring via Cisco IP SLA to measure VoIP jitter, latency, and packet loss

|Webinar: Getting a Grip on VoIP |
Introducing VoIP to your enterprise network can create more questions than answers. Pose yours to our panel of VoIP experts.
More than any other type of application, VoIP quality of experience demands optimal network performance. Adding more bandwidth won't solve all of your VoIP performance issues. Deploying server agents and probes is costly and burdensome. So, what are your other options?
During this live Q&A webcast, our VoIP panel of experts, moderated by Steven Taylor, will address your most pressing issues when deploying and monitoring VoIP performance on your network, such as:
- How is VoIP different from other applications on your network?
- Can you monitor your users' VoIP quality of experience?
- Why is it as important to measure call setup as it is to measure call quality?

|Maximizing the Value of the Phone Status Changes Incident |
Tips for Configuring Incident Reporting in NetQoS Unified Communications Monitor 2.0 and Later
The Phone Status Changes Incident report, new in NetQoS UC Monitor 2.0, was designed to help you detect failover events and outages that affect Cisco phones and Cisco Unified Communications Manager call servers running in clusters. This best practices paper provides some background information about this Incident, some tips for setting up Locations that work well with this Incident type, and advice for configuring the phone status changes threshold and Incident response action.

|Addressing Echo in VoIP Systems |
Echo is a troubling problem for telecom professionals. Most of us have suffered through a telephone call where we had to try to talk with a lot of echo on the wire. It's very distracting.
Voice over IP does not create echo. However, due to the temporal aspect of echo, VoIP systems can and do increase the amount of echo heard during a telephone conversation. Echo cancellation is one of the more complex parameters that need tuning to preserve VoIP call quality. And IP networking specialists are increasingly finding that they must understand and monitor echo cancellation to manage their VoIP system.
This white paper gives an overview of echo issues, provides a brief introduction to echo cancellation, and describes the echo metrics provided by the NetQoS Unified Communications Monitor VoIP management solution.

| Free VoIP eBook: Managing VoIP Quality of Experience on Your Network |
Network convergence offers the vision of a single network, carrying traffic from many different types of applications (voice, video, and data, to name a few). Many have been enticed by this vision. A large and increasing number of organizations have a voice over IP (VoIP) pilot or a full deployment project, either ongoing or planned for a future date. And it's almost impossible to buy a non-VoIP enabled phone system these days. In many cases, VoIP is just the entry point for rolling out new unified communications applications, such as real-time dashboards, video, and presence. Therefore, success is doubly critical for organizations deploying VoIP. Not only is phone service vital to the success of most enterprises, but if VoIP doesn't work well, the results are delays when deploying other, related applications, as well as long-term ramifications that are harder to predict.
A performance-first approach to network management is never more important than when deploying VoIP. In the early days of VoIP technology development, concern centered around call server uptime. Today, VoIP systems have matured to the level that you can move beyond making them work to making them work well. Now the focus has shifted to making VoIP perform well.
The task of making VoIP perform to the highest possible standard increasingly falls to you-the converged network manager. In the past, the network manager was responsible for the network only, and didn't need specialized application expertise. Convergence is changing all of that.

|Expert Data Acquisition |
This document explains the concepts and tools available for passively acquiring network data for analysis. Following the methods outlined here can prevent issues like duplicate packets, asymmetric traffic, and oversubscription of switch ports. These best-practice methods ensure that metrics calculated from captured data will be accurate and reduces unnecessary load on network monitoring tools. This document is intended for network engineers and for the administrators of monitoring platforms who wish to learn which techniques are best suited for their environment.
