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 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:
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).
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.
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.
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.
Reports for call traffic that happened days⁄months ago together with interface error & utilization reports help in trending, analysis & capacity planning of network resources. An immediate dashboard view of Top 10 call path reports by MOS, Packet Loss, Jitter, Latency, Maximum SLA violation and Maximum RTT ensures that you are in the know of likely problem areas. With 100+ reports readily available, OpManager is one of the best VoIP monitoring tool available in the market. The reports include:
OpManager’s VoIP monitor automatically enables Cisco IP SLA in selected source routers. A VoIP template allows you to easily simulate different traffic loads so as to analyze VoIP service performance over varying VoIP traffic loads. All the threshold limit settings for alerts and alarms are also customizable for effective Cisco VoIP performance monitoring.
OpManager does much more than just monitor VoIP performance, it alerts you of poor performance, and assists you with detecting the root cause of VoIP issues and troubleshooting them. Its seamless in-house add-on with NetFlow analyzer lets you monitor traffic patterns to further complement VoIP monitoring. If you're searching for the best VoIP monitor, then look no further!
