How Vested Networks increases reliability and customer trust with Sinch

Vested Networks is a Texas-based business phone provider that prides itself on its “down-home customer service”, promising that customers can reach a human support agent within 15 seconds. They serve more than 1,200 businesses across the U.S., from single-line offices to county governments and major medical providers. 

As CEO and founder Evan Huff explains, Vested Networks exists to “take all the headache out of business phone systems.” That means white-glove onboarding, simplified billing, concierge-level support, and the rare ability for customers to call and instantly get answers — no endless menus, no bots, and no long wait times. 

But delivering that experience at scale isn’t easy. Vested Networks needed absolute confidence in its voice and messaging delivery infrastructure to make it happen. Uptime, call quality, and routing reliability aren’t just technical metrics to them; they’re the backbone of their promise to customers who depend on phone service for critical operations. 

“We have people’s lives on the other end of these calls,” Evan said. “If a hospital, sheriff’s office, or government office can’t get through, that’s not a minor inconvenience. We have to deliver 100% of the time.” 

To meet that standard, Vested Networks relies on Sinch as their primary carrier for inbound and outbound voice and messaging services. 

Sinch powers almost all of Vested’s communications touchpoints: elastic SIP trunking, nationwide numbering, toll-free services, messaging, CNAM Caller ID, and dynamic E911. With Sinch’s Super Network as the core, Vested can confidently serve diverse industries, from rural municipalities to large medical groups, without worrying about limitations that some traditional carriers impose. 

Sinch’s flexibility also enables Vested Networks to deliver capabilities can’t like posting numbers in hard-to-reach rural areas where other carriers can’t support transfers. This has become a major differentiator for the company and an important resource for underserved communities. 

Vested Networks also uses Sinch’s services to enable SMS services on phone numbers, letting their customers send promotional messages, alerts, and appointment reminders out to their end users. 

Vested Networks is an unusual partner in the telecom world, because their team is deeply technical and handles Tier-3-level diagnostics internally. They troubleshoot their own interconnection issues, identify upstream routing problems, and often pinpoint the root cause faster than traditional carrier support teams. 

This speed is critical for regional the regional governments, medical offices, and emergency lines they support — and Sinch’s tools and direct lines of communication help make it possible. 

“When we reach out, it’s because we’ve already diagnosed the issue,” Evan said. “Sinch connects us to the people who can actually help resolve it. That’s invaluable.”  

With help from Sinch, Vested Networks has grown from a two-person operation in 2018 to more than 1,200 customers, 20,000 numbers under management, and consistent growth in daily call volumes. Today, they support more than 600 simultaneous calls during peak hours — all with the stability and confidence their customers expect. 

Together, Sinch and Vested Networks share a commitment to reliability, transparency, and customer-first service. This partnership enables Vested Networks to deliver the fast, frictionless, human support that sets them apart.
