VoIP Monitoring Software
VoIP Performance Monitoring with PRTG
PRTG is Paessler's easy-to-use VoIP monitoring software which allows you to monitor VoIP performance.
VoIP related network traffic is especially sensitive to even slight problems in connectivity. The sound quality of VoIP calls drops dramatically when UDP packets are not received in a timely fashion, if packets are lost or reordered. VoIP monitoring software gives you the possibility to act quickly and proactively, maintaining a high quality of service and avoiding the economic costs of downtimes.
PRTG offers you two ways for VoIP performance monitoring
- Cisco® IP-SLA
- built-in QoS measurement
VoIP Monitoring using IP-SLA
Wikipedia describes IP SLA as "a feature included in the Cisco IOS Software that gives administrators the ability to Analyze IP Service Levels for IP applications and services. IP SLA's uses active traffic-monitoring technology to monitor continuous traffic on the network. This is a reliable method in measuring over head network performance." IP-SLA is mostly used for VoIP performance monitoring.
This VoIp monitoring manager is only available in the more expensive boxes from Cisco. If you don't have IP SLA capable routers/switches you can still get similar information with our QoS Monitor which does not require any special hardware - just two PCs running Windows. If you do own hardware which supports IP SLA then PRTG VoiP Monitor brings you probably the least-cost monitoring solution for IP SLA. Most vendors charge extra for IP SLA support (a thousand bucks and more). Following Paessler's long term policy we simply include this as one of our sensor types. You can even use the PRTG Freeware Edition for VoIP monitoring with IP SLA!
QoS Monitor
The QoS Monitoring Sensor monitors the quality of a network connection by looking at "quality of service" parameters like VoIP jitter, packet loss, packet delay variation, duplicate packets and other readings.
This VoiP Monitoring software works by sending UDP packets between two remote probes. This is the perfect VoIP monitoring tool, enabling you to find network issues such as packet delay, jitter, and packet loss that can affect VoIP sound quality.
