Handheld VoIP tester

NetTool VoIP covers the entire spectrum of tasks required to deploy IP phones to the desktop.

The handheld tool decodes and displays boot events, call control and call quality information.

The boot log displays key events such as DHCP address acquisition, DNS lookup of call servers and gateways, downloading operating files and call server registration.

It supports troubleshooting of the IP phone boot process including physical layer tests of structured wiring, patch cables, switch port configuration, VLANs and PoE voltage.

The VoIP log displays call control events, QoS configuration and call quality metrics. The log records call setup, configuration and tear down of a call in progress.

As the call proceeds, the RTP configuration is displayed including IP addresses and ports used, VLAN priority or Diff Serv and CODEC. Once the call is completed, the log displays the RTP quality metrics such as jitter and dropped packets.

The VoIP monitor feature tracks call quality in progress by measuring the RTP stream and displaying the number of frames, dropped frames, out of sequence frames and jitter.

The monitor also displays RTCP endpoint information such as jitter and dropped packets. Statistics are available for both the phone side and the network side while a call is in progress.
