SIPPIO —
Certified Microsoft Teams Voice & Avaya Migration

SIPPIO is a Microsoft-certified voice provider specializing in connecting Microsoft Teams to the PSTN (public telephone network) — enabling enterprise voice calling through the Teams interface. SIPPIO delivers certified Direct Routing, Operator Connect, Teams call quality and compliance reporting, and guided migration services for organizations moving from Avaya and other on-premises PBX systems to Teams voice. SIPPIO's focus is exclusively on the Microsoft Teams voice ecosystem, making it a specialist provider for organizations standardizing on Teams as their primary communications platform.

Both Direct Routing and Operator Connect connect Microsoft Teams to the PSTN, but they differ in architecture and management. Direct Routing connects Teams to a Session Border Controller (SBC) and a PSTN carrier — giving organizations more flexibility and control, including the ability to use existing SBCs. Operator Connect is a Microsoft-managed program where certified operators (like SIPPIO) connect directly to Microsoft's Teams infrastructure through a managed API — provisioning and managing PSTN calling directly in the Teams Admin Center with simplified setup and fewer on-premises components. SIPPIO is certified for both, and the right choice depends on existing infrastructure, compliance needs, and IT management preferences.

SIPPIO provides a documented migration path from Avaya on-premises PBX infrastructure to Microsoft Teams voice — covering number porting, SBC configuration, Direct Routing or Operator Connect setup, and user migration sequencing. For organizations with Avaya systems approaching end-of-life or facing rising maintenance costs, SIPPIO's Avaya migration service provides a structured transition to Teams voice with a certified partner that understands both Avaya architecture and Teams requirements. Migration can be phased to minimize disruption to ongoing operations.

SIPPIO Teams Reporting and Analytics extends beyond what the Microsoft 365 Admin Center natively provides — delivering detailed call quality monitoring, usage reporting, and compliance reporting for Teams voice deployments. Organizations can track call quality metrics, identify network-related call degradation, monitor user adoption across the Teams phone deployment, and generate compliance reports for regulated-industry requirements. This is particularly valuable for IT teams managing large Teams voice rollouts who need operational visibility into call performance beyond the default Microsoft reporting.

SIPPIO's services are built entirely around the Microsoft Teams platform — Direct Routing, Operator Connect, Teams analytics, and Avaya-to-Teams migration. Organizations not using Teams as their primary communications platform, or those evaluating UCaaS platforms without a commitment to Teams, would not benefit from SIPPIO's specialized capabilities. SIPPIO is the right fit for organizations that have already chosen Teams or are actively planning a Teams-first communications strategy.
