Ribbon SBC-1K-LIC-FXO 4 FXO Port License

Add analog trunk connectivity to an existing Sonus SBC1000 deployment with a license that enables 4 FXO ports. This is the right fit when voice teams need to bridge legacy PSTN services into a modern session border controller environment while keeping the platform footprint unchanged. For enterprises maintaining mixed telephony estates, FXO capability can be the difference between a clean migration path and a costly hardware refresh. This license extends the SBC1000 so it can interface with analog lines where they still matter — branch survivability, legacy carrier handoffs, or transitional voice architectures. Because it is a licensing add-on rather than a separate appliance, procurement stays focused and deployment remains tied to the installed base. That makes it a practical choice for organizations that need precise port expansion, controlled spend, and compatibility with an existing Sonus SBC1000 Session Border Controller environment.
