What does a VoIP monitor do?

A VoIP monitor tool leverages Cisco's IPSLA technology to generate synthetic traffic and monitor call quality as experienced by the client. As opposed to passively monitoring VoIP metrics, IPSLA technology allows IT admins to be proactive and detect potential issues before they occur. This allows organizations to comply with stringent SLA metrics easily.

Cisco IPSLA technology creates traffic between two devices. A VoIP monitoring tool collects metrics from them and presents them to you. The router that generates VoIP traffic is called the IPSLA router while the router that receives the traffic is called IPSLA responder. IPSLA responders are not necessarily needed for VoIP monitoring, but you can gather more detailed metrics with them.

OpManager: A complete VoIP performance monitor

OpManager helps you adhere to service level agreements by monitoring call quality metrics like Jitter, packet loss, and mean opinion score. When these metrics cross thresholds set by you, it generates alerts and notifies you using channels like SMS, email, slack or webhook. OpManager also monitors device availability and performance metrics like CPU, memory, and disk space. You can also perform granular network traffic analysis using the NetFlow add on with OpManager.

OpManager's Voice over IP tool helps you:

The new VoIP management addition to OpManager provides a clean, centralized monitoring center for your VoIP network. Being able to always view the top call statistics allows you to quickly identify any possible issues. Another key feature is the report section where historical data can be used to view trends in performance.

VoIP monitoring using Cisco IP SLA

Proactive VoIP performance monitoring

OpManager's VoIP monitoring solution proactively monitors and reports on the WAN infrastructure’s capacity to handle VoIP calls. Using Cisco IP Service Level Agreements (SLAs), OpManager simplifies VoIP Monitoring and continuously measures critical Quality of Service (QoS) parameters of VoIP services to provide insights on VoIP network performance. VoIP quality metrics measured include packet loss, delay, jitter, the Mean Opinion Score (MOS) and Round Trip Time (RTT).

VoIP Monitoring Tool - ManageEngine OpManager

Monitor VoIP quality across WAN infrastructure

Since the cloud is the communication medium, a VoIP calling endpoint never gets a dedicated end–to–end line unlike traditional circuit–switched networks. This can bring nightmares to network personnel who maintain VoIP call quality. They need continuous network health status of not just their own corporate WAN, but also that outside WAN precinct, through to ISP network(s). By virtue of the Cisco IPSLA technology present in a wide number of network devices, VoIP monitor software provides in–depth QoS visibility over call paths within WAN and also for calls between corporate users and other users in ISP networks.

VoIP Monitoring Solutions - ManageEngine OpManager

Easily troubleshoot poor VoIP performance

Does huge packet loss happen during high bandwidth usage hours? Which user or which type of traffic consumed most bandwidth? OpManager’s VoIP monitoring software has in-depth NetFlow traffic reports placed alongside VoIP QoS trend graphs to help in quickly troubleshooting VoIP performance problems.

Report on Source and Destination performance

The originator of a call could be within the corporate WAN and the called party could be located outside in the ISP network, or vice versa. VoIP management software provides Source-to-Destination and Destination-to-Source statistics on packet loss monitoring metrics, delay and jitter values. You can now easily find out which side of the call faced poor VoIP quality and why. Let OpManager take care of your networks' VoIP performance monitoring.
