OGS selected the Empirix service assurance monitoring solution to gain visibility into the international connections providing carriers with access to its voice (both legacy circuit-switched and VoIP) and 2G/3G roaming services. With Empirix, OGS has uninterrupted visibility of network performance and service quality, as well as the ability proactively identify potential issues before they negatively impact customers. This flexible solution is capable of adapting to new technologies and innovative new services; OGS plans to extend the Empirix solution’s coverage to a recently announced LTE roaming service.
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.
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.).
Voice over LTE (VoLTE) holds major potential for Mobile Service Providers (MSPs), including the promise of a better user experience, increased cost efficiencies, differentiated Voice Quality of Service (QoS), and more. Yet these mind-blowing potentials don’t come without a price. The world of VoLTE is very complex and it takes some real planning to fully understand and handle […]
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.
Whether you are setting up a new contact center environment or updating an existing one, there are many factors to take into account. One wrong move and when you go live, the whole structure can come tumbling down. That’s why thorough pre-deployment testing is crucial.
To start the process off, perform a “Network Readiness Assessment” or NRA. Note, however, that this concept means different things to different people. I have seen some customers perform NRAs on their own in a variety of different ways, I’ve seen third parties perform them for customers, and some IP Telephony vendors require that the NRA be performed by them in order for them to support their product.
