The “QoE Index” estimates end user perception of any service Today we proudly announced that our innovative new approach to scoring Quality of Experience (QoE) across telecommunication services has been granted a US patent. Designed by Angelo Baccarani, Product Manager for NFV Service Assurance at Empirix, the scoring model provides a single score, known as […]
Since the introduction of VoIP, the service or underlying technology (based on the SIP protocol) has been susceptible to multiple fraud scenarios. In particular, by exploiting some of the features of VoIP, such as three way call and call transfer, hackers can inject call signals into the network and effectively hijack calls. The result is significant […]
For both fixed and mobile service providers, maximizing the effective use of network capacity is becoming key to increasing revenues and assuring the quality of experience for customers. Driving bandwidth consumption are services such as Voice over IP (VoIP or Internet telephony), video on demand (VoD), and the more conventional data services such an internet […]
Over the past few months, I’ve talked about the importance of communications network testing end to end. Today I’d like to bring the idea through to its logical conclusion. Read: The Right Ingredients to Build an Impactful Testing ROI Case I’ve consolidated below some real life use cases into a single connected view of end […]
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.). Previously, I outlined Mean Opinion Score (MOS) and described why it has become the de facto standard […]
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. If you are not using an automated system to calculate MOS, you need the following things: A group of people to serve as test […]
Previously, I discussed the first step in end-to-end testing: look at your infrastructure. Let’s take a look at what to do after testing the infrastructure: application and voice quality testing. The basic procedure is accomplished by automating actual calls into the voice application server in a controlled manner and measuring the results at every stage. […]
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. Monitoring Your Communications Systems There […]
For most Americans, 2014 marks the year the Affordable Care Act goes into full effect. But for healthcare companies, now is the time to prepare. There are more than 48.6 million uninsured people that will require coverage. Knowing that these people will have plenty of questions, healthcare companies nationwide are updating their contact centers and preparing […]
