What Sippio does

SIPPIO is a privately held voice enablement platform, founded in 2019 and headquartered in Annapolis, Maryland, that automates the delivery of PSTN calling services inside the three major enterprise collaboration suites: Microsoft Teams, Zoom Phone, and Webex by Cisco. The platform is built as a 100% Azure-native architecture with automated provisioning, REST APIs/microservices, E911 management, number porting, DID inventory, and a CPQ system, enabling partners to activate customers in minutes rather than the weeks or months typically required for Direct Routing deployments. SIPPIO operates a channel-first go-to-market, with named partners spanning tier-1 carriers (AT&T, Vodafone, Enreach, Redcentric, BTS), master agents and distributors (Pax8, Jenne), and dozens of MSPs and system integrators across 80+ countries. End-customer use cases cut across enterprise, SMB, higher education, and non-profit segments, with named customers including Roseman University, the Museum of Fine Arts Boston, Friedberg PC, Amplitel Technologies, eGroup, and G. Modiano.

The company monetizes primarily through subscription-based voice services (consumption-based or all-inclusive per-seat/per-minute plans configured via Partner Portal CPQ), supplemented by managed services revenue through the SIPPIO Care 24/7 support program, and increasingly through AI-powered BI (SIPPIO Beacon), channel marketplace and loyalty programs (Partner Exchange, SIPPIO Rewards), and analytics/messaging add-ons (Analytics 365, Clerk Chat, Tango Networks). SIPPIO holds Microsoft Co-Sell Preferred status and Operator Connect accelerator designation, is a Zoom Cloud Peering partner in the Zoom Provider Exchange, and integrated with Webex by Cisco in June 2025, completing its tri-platform footprint. The company has received Frost & Sullivan's 2023 North American Product Leadership Award and multiple TMC/TMCnet awards in 2023 and 2025, and is led by founder/CEO Adam Cole with a leadership team drawn from Microsoft, Avaya, Tata Communications, and SYNNEX.

• Bandwidth Inc. Bandwidth is a communications platform operator with its own global voice network and Operator Connect/Microsoft Teams integrations, competing with SIPPIO for direct routing minutes and number inventory.
• Ribbon Communications: Ribbon provides SBCs, SIP trunking, and Microsoft Teams certified voice infrastructure — overlapping directly with SIPPIO's direct routing and voice enablement offering.
