Verifying Voice over IP Service

Introduction

With the VoIP (Voice over IP) option enabled, you can use NetTool to verify VoIP service on a link. NetTool can track SCCP/SIP call control and measure RTP quality of service. The VoIP Log and VoIP Monitor capture call transactions, providing you with a step-by-step record of major events so that you can troubleshoot problems with VoIP service.

Note

Keeping your NetTool updated ensures that you have access to new call control protocols as they become available. For update instructions, see “Updating NetTool’s Software” in Chapter 1.

Running AutoTest

To begin testing, do the following:

1.Connect NetTool inline between the network and a PoE-powered device (see “Inline Connection” in Chapter 2).

Caution

When operating inline with a POE-powered device connected to NetTool, make sure that NetTool is not plugged into the AC adapter or into a serial device that is grounded or damage may occur to the equipment.

2.Run AutoTest (see” Running AutoTest” in Chapter 3).
