Keep enterprise voice services under control with perpetual on-prem DSP licensing sized for 1,001 to 1,500 users. Built for organizations that prefer fixed-capacity planning over recurring subscription exposure, this package supports a stable deployment model for communications teams managing long-lived infrastructure. For procurement and architecture teams, perpetual licensing reduces renewal churn and makes budgeting more predictable across multi-year planning cycles. It is a practical fit for environments where consistency, governance, and clear ownership matter more than short-term flexibility. That makes it especially relevant for organizations standardizing on-prem communications platforms and maintaining service continuity across distributed sites. This license is positioned for teams that need to preserve voice processing capacity without introducing unnecessary complexity into the stack. It supports a disciplined approach to scaling, where capacity is matched to a defined user band and procurement can be aligned to operational demand. For enterprises that still run critical communications on-prem, that clarity has real value.
