This certification enables agencies to use Empirix test automation to most efficiently, accurately, and cost effectively simulate and test national and regional disaster scenarios, including encrypted communication performance, at high call volumes. This stress testing measures actual voice quality and adjunct systems, such as call recording, in order to ensure their viability in critical scenarios.
Empirix, Inc., the recognized leader in contact center assurance and end-to-end network performance visibility, today announced that its VoiceWatch cloud-based monitoring service detected a service disruption in one of the nation’s largest toll-free networks and notified affected Empirix customers within seconds of the disruption occurring.
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.).
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.
As we enter early summer, it’s time to take a look back at IAUG, as well as the third consideration for a migration to SIP: what happens once you go live. Prior posts in this series focused on design and core technology decisions and up through the point of testing just prior to go live, […]
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.
When I talk about end to end SIP I am looking at SIP all the way in from the carrier trunks, through the core infrastructure, and out to the phones (hard phones or soft phones). With that out of the way, let’s talk more about some of the questions that need to be answered and some of the key things that you, the customer, need to do in order to make your SIP deployment successful.
