VI is a privately-held, Pittsburgh-based technology company that specializes in wholesale SIP trunking offered primarily to resellers, service providers, MSPs, and call center customers across North America, utilizing a recurring revenue model. VI has over 1,400 customers (with no significant customer concentration), about 35 employees, and has been growing consistently the last several years.
The company also recently launched a communications platform as a service (or CPaaS) product. CPaaS enables developers to add communication capabilities (such as voice, video, messaging, etc.) to their software and web applications without having to be communications nor networking experts.
Sangoma’s pedigree in the SIP trunking business is underscored by its performance in the recent report titled “2019 SMB SIP Trunking Customer Satisfaction,” conducted by the Eastern Management Group. The report details a survey of 3,000 IT managers in a side-by-side comparison of 29 SIP trunking providers. Customers evaluated their SIP vendors on six Ccustomer satisfaction measurements under the headings of product, vendor experience, and customer delight. In Eastern Management Group’s survey, Sangoma received the highest possible ranking— four stars—in every customer satisfaction measurement: technology and product, purchase experience, support, management tools, total overall satisfaction, and recommend-to-a-friend.
