Avaya Secure Cloud Audio w/PSTN 1Y 15K+

Maintain voice access for critical meetings with Avaya Secure Cloud Audio with PSTN, sized for the 1-year 15K+ tier. This subscription is designed for organizations that need stable conference calling across distributed teams, external stakeholders, and time-sensitive operations. PSTN access gives participants a familiar dial-in path when network conditions, device constraints, or policy restrictions make app-based joining impractical. For procurement teams, the value is in predictable coverage and a service model aligned to enterprise conferencing demand. Audio-only conferencing remains the most reliable option for many workflows: incident bridges, executive updates, vendor coordination, and customer support escalations. By pairing secure cloud audio with PSTN connectivity, this offering supports participation across office, remote, and mobile users without forcing a single endpoint strategy. Choose this tier when you need a controlled, subscription-based conferencing service for large-scale usage and want to keep collaboration accessible without adding unnecessary complexity. It fits organizations that prioritize reach, consistency, and operational discipline in their communications stack.
