VoIP and Network Monitoring Services

VoIP Monitoring

Comprehensive VoIP Quality Monitoring System

• Quickly discloses where a VoIP call went bad and why via the Call Path mapping report
• Unique single-ended Call Simulator performs test calls to any intermediary IP address
• Easily locate where VoIP phones are connected to the network, down to the switch and port
• Includes all Network Monitor features

Complete Call Path Mapping
Perform a complete “layer-2 traceroute” to determine every cable span involved in passing traffic between two IP phones and quickly learn which links are discarding packets at the time of a bad call.

Asymmetric Routing Check
The Call Path report permits you to perform a reverse call path mapping so you can check the forward path and reverse path to make sure they both use the same path through the network.

Evaluate Current In-Progress Calls
The Call Path report permits analysis of current, in-progress calls by evaluating bandwidth utilization of all involved links.

Rapid Assessment of WAN Links
The Assessment report quickly displays your WAN’s ability to handle VoIP calls, including the number of concurrent streams that can be handled by each link.

Easily Find Mis-Configured Cisco QoS
The Queuing configuration of interfaces are queried on interfaces along the path. This makes it easy to see if a link has the correct queueing configuration for the available bandwidth.

NAT Troubleshooting Tool
The Tools tab provides a quick NAT troubleshooting tool to help determine if NAT is occurring somewhere between a VoIP phone and the VoIP Monitor server. This can help resolve one-way voice problems.

Powerful Call Simulation
Call simulation technology is significantly different from other call simulators.

The first difference is that it doesn’t require you to install any software. It’s a single .EXE file that can be run from any computer, server, or even VoIP gateway. This makes it very easy to run from virtually any location on the network.

The second difference is that it doesn’t require you to install or run an agent on the remote end of the network. Any IP address that responds to an ICMP echo request can be utilized as a valid endpoint for testing. This means you can use the IP address of a VoIP phone or gateway, or even the IP address on an intermediate switch or router to test individual segments of the network.

Thus, different sections of the network can be quickly tested to determine which link induces packet loss, latency, or jitter.

The number of calls can be dynamically changed to see how the network responds to the increase in load.

Phone Locator
All VoIP phones & Gateways are identified on the Phones report along with the switch and port where they are connected. Each phone shows the endpoint health (error and utilization rate) to insure that all VoIP endpoints have healthy network connections.

Network Monitoring Service

Advanced Network Performance Monitoring System

• Automatically tracks performance and errors of all links in the network
• Deploys and auto-discovers all network devices and interfaces in minutes
• Tracks current and historical utilization, errors, and broadcasts
• Rapidly configure alerting with our WildCard alerting mechanism

Rapid Auto-Configuration
Automatically scans the network to learn about network devices that can be monitored. Interrogates each device
to learn the most efficient method to monitor. Easily add/remove network sites or individual devices.
• No SNMP MIB or OID research/evaluation required
• Completely device agnostic (Cisco, Nortel, Extreme, Brocade, Dell, HP, Netgear, Linksys, etc.)

Complete End-to-End Monitoring
Tracking errors on all interfaces on your network provides you with an unabridged vision of your network’s health.

Monitor Live WAN Utilization
The Dynamic Network Map presents all of your WAN interfaces on one graphical map interface so it’s easy to see your entire network’s usage from one glance. Links are updated every 5 seconds.

Optimized for large-scale NOC monitoring implementations, this map can be viewed by multiple browsers without increasing queries on the network. A full-screen detached view is provided for maximum visibility.

As links become saturated, they become redder in color and fatter so it’s easy to determine which links are heavily utilized.

Automatically Document Your Network
Network Monitor collects and displays the OSI services that each device reports. This lets you rapidly and accurately determine the purpose and function of each network device without having to perform a manual interrogation.

Compile Network Inventory Instantly
Each device on your network is interrogated for information about its OS version, physical location and administrative contact. This provides an efficient method to track device inventory information across the entire network.

Locate IP Addresses on your Network
Finding which switch port has an IP address connected is now an easy task with the tools provided by Network Monitor. Just enter the IP address on the Tools tab and all of the monitored ARP caches will be searched for that IP address. Once the MAC address is found, you can search all of the switch ports for that MAC address and quickly discover the interface you are looking for.

Monitor Network Device Uptime
Each device reports how long it has been online and servicing the network. This determines the general reliability and stability of each device that provides services for your network. Being familiar with this statistic helps evaluate when equipment should be replaced or serviced
