An international company that outsourced technical support and customer service to a wide range of international clients mostly depended on their Issabel PBX system. With call centers located in North America, Europe, and Asia, their operations cover multiple continents. Their voice communications relied heavily on this technology, which handled thousands of international calls every day. However, it was becoming less reliable.
The Challenge: Bridging Continents with Flawless Communication
For the BPO provider, maintaining consistent call quality and connectivity throughout their global network was a major challenge. Despite its versatility, its Issabel platform had several monitoring issues:
- International Call Failures: Sometimes, calls to and from specific international locations would either not connect at all or had poor voice quality (echo, delay, robotic voice). It was difficult to determine if these were carrier issues, local network problems, or Issabel setup errors at a particular location.
- IVR Inconsistencies Across Regions: Depending on the caller’s origin, their multilingual IVR system, which was intended to direct them to the proper language and support queues, occasionally displayed distinct behaviors or response times.
- SLA Compliance Concerns: The corporation had strict Service Level Agreements (SLAs) with its clients regarding phone system uptime and call answer rates. Any downtime or persistent call quality issues put these SLAs at risk.
- Difficulty in Proactive Outage Detection: It was a reactive procedure that was frequently started by agents or customer complaints to find carrier-level outages or problems with certain international routes before they affected a significant number of calls.
- Ensuring 24/7 Accessibility for Global Clients: With clients and their customers in various time zones, their Issabel system needed to be fully operational around the clock.
They required a comprehensive monitoring solution that could:
- Check international phone number availability: Specifically testing connectivity to and from their key international operational hubs.
- Monitor phone lines from multiple locations: Simulate calls from various geographic points to test the experience of their international callers.
- Detect phone carrier-level outages: Identifying broader network issues that could impact their Issabel system’s connectivity.
- International dialing test automation tool: Regularly verifying that outbound international calls could be successfully completed through their Issabel setup.
- Phone tree (IVR) testing automation: Ensuring their complex, multilingual IVR was functioning correctly for all user groups.
- SLA compliance monitoring for voice services: Providing tangible data to demonstrate adherence to client SLAs.
- Voice system health monitoring dashboard: A centralized view of their global Issabel infrastructure’s performance.
The Solution: Global Issabel Monitoring with PhoneNumberMonitoring.com
PhoneNumberMonitoring.com and the BPO provider partnered to put in place an advanced monitoring plan customized for their international Issabel environment. The goal was to gain deep visibility into their global voice operations and proactively address issues.
The deployment included:
- Multi-Location Phone Service Testing Platform: PhoneNumberMonitoring.com initiated calls to the company’s numerous call center numbers from a variety of international locations by using its global network of testing nodes. This simulated their international clients and their customers’ actual experiences.
- Automated International Dialing Tests: To confirm route availability and connection quality, scheduled outbound test calls were placed from the Issabel system to a predefined list of international numbers.
- Comprehensive IVR Testing Automation: The platform carefully tested every branch of its multilingual IVR from various geographic angles, making sure that the prompts, selections of languages, and agent queue routing were all correct. This involved tracking the response time of the IVR system at every stage.
- Real-time Phone Number Availability Checker: Continuous monitoring of all critical inbound international toll-free and local numbers ensured immediate detection of any reachability issues.
- Voice Quality Monitoring: In order to notify the BPO of the potential degradation in call quality, the system analyzed test call audio for metrics such as jitter, latency, and packet loss for important routes. This acted as a voice connection health checker tool.
- Alert System for Failed Inbound & Outbound Calls: Any failed test call, whether inbound or outbound or any IVR navigation error, triggered immediate, detailed alerts to the corporation’s central NOC and regional IT teams.
- Enterprise Phone Line Diagnostic Software (Features): For each failed test, the platform included advanced diagnostic information that helped in promptly determining if the issue was with their Issabel configuration, a specific SIP trunk, or an upstream carrier.
The Results: Enhanced Global Call Reliability and SLA Adherence
The implementation of PhoneNumberMonitoring.com’s Issabel monitoring brought about transformative improvements for the multinational corporation:
- Improved International Call Success Rates by 25%: By identifying and fixing problematic routes and carrier difficulties much more quickly, the international dialing test automation tool and check international phone number availability features greatly increased connection reliability.
- Consistent IVR Performance Globally: Their multilingual IVR worked as expected for all users, no matter where they were, due to automated testing. The number of successful IVR navigations increased by 15% as a result.
- Proactive Detection of Carrier Issues: The company was able to divert traffic or alert customers in advance after the system effectively discovered multiple carrier-level outages impacting particular regions before they caused major disruptions.
- Strengthened SLA Compliance: An independent monitoring platform’s documented uptime and call success data allowed the BPO to show that they were adhering to their clients’ SLAs.
- Reduced Mean Time to Resolution (MTTR) for Voice Issues by 50%: Their IT teams were able to troubleshoot and resolve complicated international voice issues considerably more quickly due to the voice system health monitoring dashboard’s comprehensive alerts and diagnostic information.
- Optimized Routing and Carrier Selection: Insights from the monitoring data allowed the company to make more informed decisions about their international carrier relationships and Issabel routing configurations.
- Ensured 24/7 Phone Number Accessibility: The constant monitoring gave them the assurance that their phone lines were always open, which was essential for their international operations.
Conclusion:
For a multinational BPO, reliable international communication through their Issabel platform is essential. By addressing the complex nature of their global operations, PhoneNumberMonitoring.com provided a comprehensive solution that allowed them to test international dialing, proactively monitor call availability, guarantee IVR integrity, and ultimately improve customer satisfaction and operational stability. This case study demonstrates how companies may overcome the difficulties of overseeing complex, global PBX systems like Issabel with the use of specialized monitoring.
