The challenge: SIP infrastructure replacement
A national manufacturer and supplier of building materials wanted to replace its existing SIP infrastructure to improve reliability, scalability, and security. Their existing provider’s upstream carrier had been hit by a DDoS attack, creating a major outage that caused service disruptions over the course of two weeks. Reliability and redundancy were obviously a critical must-have for the new solution, but that wasn’t their only requirement. The new provider needed to support high volumes of simultaneous calls with superior voice quality.
The company also wanted a future-proof solution that would integrate seamlessly within their existing IT environment and accommodate fast growth and ongoing technological advancements. Their immediate need was for 25,000 direct inward dial (DIDs) and 80 toll-free numbers with 640 concurrent call paths shared between and available to two data centers. But they were acquiring companies at a fast clip, so this would balloon very quickly to 1,500 locations with 50,000 DIDs and sufficient concurrent call capacity to accommodate peak usage.
Finally, the solution needed to offer easy-to-use self-service capabilities they were currently lacking. With no portal or access to information about their inventory, they had to manage everything manually with spreadsheets, which was incredibly time-consuming and error-prone. And when they needed support from their current provider, it was a frustrating experience, everything—even just getting answers to basic questions—took too long.
The solution: Easy, reliable, scalable SIP
After evaluating a number of potential providers, the company selected Pure IP’s Global Voice. The solution checked all the boxes: cost-effective, high-quality voice and concurrent call capacity with burstability; a single management portal for invoicing, call reporting, trunk utilization, DID management, and inventory; integration with ServiceNow; and support for a future cloud journey with the ability to migrate to Cisco Webex. Most of all, Pure IP was able to offer something no other provider could: HyperNetwork™ , the patented technology that enables the dynamic change of inbound DIDs for an unprecedented level of business continuity.
Not only did Pure IP provide the company with the most comprehensive and professional response to their RFI, including diagrams and documentation, but we followed it up with an implementation team and strategy tailored to their needs.
The result: Fast onboarding of thousands of DIDs
Because of the large number of DIDs and the need to migrate as quickly and efficiently as possible, the porting strategy was developed on a per-site basis. Thanks to smart planning and coordination, the trunk route was turned up very quickly with testing beginning the following week. Then smaller sites were ported over as a test to iron out the process so that full-scale porting could be as fast as possible. The team was able to onboard 25,000 DIDs within 6 months and is on track to expand to 50,000 six months after that. Successfully handing these volumes—there can be 80 ports in one week alone—is possible thanks to weekly cadence calls and lots of communication. And while the company was prepared for the large number of letters of authorization (LOA) needed, displaced carriers can often be strict so those documents require impeccable accuracy, and the Pure IP project team applied their expertise to help the company identify issues with rejected LOAs to keep the process moving forward.
