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.
Providing a high quality customer experience is critical to keeping your customers happy. That’s the philosophy behind the service quality assurance and analytics solutions Empirix has brought to market. We know it’s vital that, when customers contact a business, they are able to get through without long wait times, garbled conversations, incorrect transfers, constantly repeating the same information, and the like.
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.
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.
Today’s communication environment is extraordinarily complex. We live in a time where everyone wants to communicate and interact in their own unique way. Clearly this situation can be very challenging for contact center operations managers. There is pressure to meet customer satisfaction goals and reduce the risk of new technology, while also keeping costs low and addressing other business goals.
