Ribbon SBC-1K-LIC-FXS 4 FXS Ports

Add 4 FXS ports to the Sonus SBC 1000 with a license built for focused expansion. This entitlement is a practical fit when an SBC deployment needs analog endpoint support for fax devices, legacy handsets, or other FXS-connected equipment. Instead of forcing a broader platform change, it extends the existing controller with the exact port count required. For procurement and infrastructure teams, that precision matters. It keeps licensing aligned to the actual deployment need, avoids unnecessary overspend, and preserves the value of the installed SBC 1000 base. Whether you are supporting a small office, bridging legacy voice equipment into a modern session border controller environment, or adding a limited analog edge to a larger communications stack, this license provides a clean, controlled path forward.
