Today’s communications environments are very complex. If you’re not monitoring your systems on a consistent and constant basis, you will undoubtedly run into trouble. At the same time, a comprehensive solution has to have a variety of functionalities in order to successfully monitor this type of environment.
In one recent test Empirix was involved with, callers were complaining about long connection times and poor voice quality during a storm. The company involved conducted a test of its SBC to better understand the origin of the issue. During the test process, the organization discovered that, while having a registration flood of 10,000 concurrent SIP registrations, SIP call setup time doubled. Moreover, jitter increased on the SBC.
Data? Communications service providers (CSPs) have plenty of it. If CSPs don’t know from Big Data, no one does. Oceans of data pour into their service operations centers every day from network elements, applications and end user devices in their increasingly sophisticated networks. But as we all know, there’s a big difference between data and […]
PESQ is a testing and monitoring related acronym that stands for Perceptual Evaluation of Speech Quality. Typically pronounced “pesk,” it is used as a means for automating the assessment of speech quality in communications networks (Unified Communications, VoIP, etc.).
Now that you’ve completed infrastructure, SBC and IVR testing, let’s take a look at the last segments of the end-to-end test best practice: CTI Data and Routing testing, and Agent Desktop Integration. CTI Data and Routing Testing CTI Data and Routing testing measures the capabilities and accuracy of the link between your IVR system and […]
In the world of communications systems testing and monitoring, MOS is an acronym for Mean Opinion Score. A MOS is used to evaluate and characterize the transmission characteristics of a telecommunications system.
The starting point is the traditional Business Intelligence (BI) infrastructure. There’s no question that it’s invaluable to have the ability to take data available and use it to better understand market demands and gain a competitive edge. A tool set was developed to handle data and allow users to come to useful conclusions. But that data was limited.
The basic procedure is accomplished in a similar way to that of testing Applications and Voice Quality. You need to automate actual calls into the voice portal/IVR in a controlled way and measure the results at every stage. This is especially important in Unified Communications and Contact Center installations, where the structures are quite complex. Isolating performance issues at each layer enables you to speed the discovery of the source of any problem that might crop up.
No matter how solid a communications system is when it’s first implemented, things tend to go wrong over time. As you add new technology, change settings, have increased voice or data volumes, and more, it becomes a requirement that you monitor your communications systems to ensure they run as expected.
Two key elements of infrastructure testing of contact centers and unified communication environments include the session border controller (SBC) and SIP trunking. To understand more about SIP testing, read SIP 101: Preparing for Successful Deployment. In this post, I will focus on the requirements of testing SBCs.
