VoIP Monitor FAQs

No, the VoIP Monitor is not a separate downloadable file. The VoIP Monitor features are in-built from OpManager builds 7204 onward. The VoIP Monitor is available as an add-on to OpManager at $995.

Your evaluation copy will have the VoIP Monitor features available if you are using an OpManager build later than build number 7204. Visit this page for upgrade procedures if you are using an older build.

You first need to ensure you are using the latest build of OpManager - Build no. 7204. The Service Packs page has the upgrade packs and fixes required to upgrade older OpManager builds to the latest build. Then purchase the VoIP Monitor Add-on license and apply it to the latest build. Visit our store to purchase the Add-on license.

The OpManager VoIP Monitor monitors critical VoIP and video Quality of Service statistics such as:

• Packet loss - the data lost during transmission (in percentage)
• Delay - the time taken for a caller's voice at the source site to reach the other caller at the destination site (in milliseconds)
• Jitter - the variation in the delay of received packets (in milliseconds).
• MOS - The Mean Opinion Score is a standard for measuring voice codecs and is measured in the scale of 1 to 5 (poor quality to perfect quality). The quality of transmitted speech is a subjective response of the listener.

OpManager VoIP Monitor relies on this technology to collect QoS metrics. The Cisco IOS IP Service Level Agreements(SLAs) is a Cisco technology use active monitoring to generate traffic in a continuous, reliable, and predictable manner, thus enabling the measurement of network performance and health. Visit this linkto know more on Cisco IP SLA.

The OpManager VoIP Monitor helps you decide on whether your network infrastructure can handle any additional traffic by way of VoIP calls or video traffic. All that is needed is two Cisco routers and the OpManager VoIP Monitor will help find the effects (such as bandwidth changes) of the proposed additional VoIP or Video traffic, apart from showing what would be the quality (packet loss, delay, jitter, MOS) of video/VoIP calls.
