Overall Satisfaction with Solarwinds VoIP and Network Quality Manager
SolarWinds VoIP and Network Quality Manager (VNQM) is used primarily by our voice team, but also on occasion by the network engineers. The tool is somewhat unique in the SolarWinds Orion suite in that it provides some WAN performance and quality data that is not available from other monitoring applications. That means that the data provided by VNQM provides a proactive perspective that can be missing in some cases.
- It provides Call Manager statistics from either Cisco or Avaya devices.
- In addition to the VoIP data, the tool also allows one to monitor ten other SLA operation types that provide WAN connectivity and quality data as well as infrastructure and application quality data.
- VNQM has the ability to search CDR/CMR records.
- VoIP gateway and infrastructure devices can also be monitored with VNQM.
- The impact on SolarWinds performance itself of configuring a large number of IPSLA operations for monitoring can be difficult to predict. It would be beneficial to have some tools that could warn or predict the results of doing so.
- Additional background information on the use case for each SLA operation type would be helpful to the user who may not be an expert in the field. The Server and Application Monitor product provides this benefit for application component monitoring.
- The tool should be engineered to allow repeated SLA node discovery for any and all nodes in the Orion Platform database.
- VNQM has enabled our network engineers to see network quality issues from the end user perspective and thus be more proactive.
- The call records searching capability is very user friendly and has made it easy for VoIP engineers to troubleshoot call issues from a single pane of glass.
- We were able to implement SLA monitoring by leveraging an existing feature of our Cisco routers. No additional investment was required.
This tool is well suited to a network environment consisting of multiple sites as long as those sites have a SLA-capable Cisco router. This allows the network engineer to essentially test any call path or meshing of call paths with synthetic VoIP operations. Additionally, since the SLA operations are "point-to-point" rather than being bound only to a central SolarWinds polling server, the data metrics provide a more complete and accurate picture of WAN performance.
