What Volli does
Volli Communications is a privately held U.S. carrier-grade voice services provider founded in 2009 and headquartered in Pickerington, Ohio. The company delivers SIP trunking (Volli Connect), Microsoft Teams Direct Routing (Volli Direct), UCaaS (Volli Business), and adjacent services (SMS/MMS, toll-free, T.38 eFax, and E911 with ELIN + PIDF-LO location tracking) under a unified One Voice platform, supported by a nationwide geo-redundant backbone with a 99.99% uptime SLA and U.S.-based 24/7 engineering and NOC support. The company has ported over 200,000 numbers and serves customers across 50+ countries, with a flagship 12-year co-development partnership with Fortinet powering FortiVoice for thousands of end customers.
The business model is subscription-based recurring revenue across all products, with metered and unlimited SIP plans, per-seat UCaaS pricing, and multi-year contract terms. Distribution is channel-first, leveraging an exclusive TSD relationship with Intelisys and a network of MSPs, agents, VARs, and white-label partners across North America, complemented by a direct inside and field sales team for enterprise deployments. Customer segments include managed service providers and channel partners (primary), mid-market and enterprise organizations consolidating fragmented telecom stacks, and vertical-specific users in healthcare, legal, and financial services requiring HIPAA-compliant fax and E911 compliance with Kari's Law and RAY BAUM's Act. The company has remained independent and bootstrapped, with no disclosed external funding or institutional investors.
