Prerequisites Requirements Cisco recommends that you have knowledge of these topics: Cisco Unified Communication Manager. G Voice over IP (VOIP) G Components Used The information in this document is not based on any specific software or hardware versions: Background Information One of the most important steps in troubleshoot voice quality related issues is isolate them, either to a particular phone, set of phones, switch, gateway, etc. This so allows for targeted troubleshooting and faster resolution of the problem. One analogy that illustrates the importance of the isolation of the issue is a lost car in an airport parking lot. Find a lost car in an airport parking lot is a difficult task, when you know that the car is in a specific section of the parking lot (section 1 for example), makes the task less daunting, but when you also have the section and row (section 5, row D) it greatly reduces the time it would take to find the car.
