Overview

Testing call volume and routing is essential for Call Centers to confirm uninterrupted operation. GL Communications can generate hundreds of calls through the PSTN – at a sustained call rate – to your Call Center to test the telecommunications infrastructure and services. These calls can be generated as a service or directly from your lab environment by deploying the Call Generation test equipment. Calls can be generated to any network including VoIP, TDM, and mobile. Tens of thousands of companies and organizations rely on Call Centers to fulfil their mission critical capabilities and business functions including:

• 911 and Emergency Services
• Customer Support
• Long Distance Services

“These Call Centers can be overloaded in disaster situations or unexpected events. Therefore, organizations use redundant telecommunications connections to the outside world (PRI, SIP trunks, etc.). It is essential to test if these trunks properly rollover under high load,” said Robert Bichefsky, Director of Engineering at GL Communications Inc.

He further added, “Stress and loading processes can help test and simulate worst case scenarios and provide confidence that the network will continue to function under such conditions. GL’s Bulk Call Generators require an advanced network appliance which can generate and sustain high volume of calls with heavy traffic. If VoIP, then packets must be generated and output with high precision timing, zero packet loss and in the proper order”.
