Salt Lake City-based CallTower secured the AVANT Top Vendor NPS in UCaaS award for the second consecutive year. The recognition highlights the company's performance in deployment, adoption, and support as evaluated by Trusted Advisors.
Why it matters
Operators evaluating unified communications providers use Net Promoter Score (NPS) data to gauge potential friction in deployment and long-term support. These metrics provide a benchmark for reliability when selecting vendors to manage remote and office-based communications infrastructure.
CallTower received the top NPS designation in UCaaS for 2026, marking the second consecutive year the company has achieved this benchmark. The firm has provided communications services since its founding in 2002.

Market Landscape

When vetting UCaaS providers, operators should look beyond marketing claims and prioritize vendor support metrics and partner feedback. Consistent NPS performance can serve as a proxy for long-term reliability in deployment and system adoption.
The takeaway
Reliability in communications infrastructure is often best measured by the experiences of peer advisors who oversee deployment. Operators should track these NPS designations as industry signals when planning major software transitions.
