Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller manages voice calls between your internal network and external SIP providers. The Ribbon SBC 1000 provides security, call routing, codec conversion, and protocol translation—essential for enterprises connecting legacy PBX systems to modern VoIP networks.
Can the Ribbon SBC 1000 connect analog phones to SIP networks?
Yes. The 4 FXS ports enable direct connection of analog telephone devices and fax machines to the SBC 1000, which then bridges them to your SIP-based network infrastructure through the session border controller's gateway functionality.
What does the PRI port do on this hardware configuration?
The 1 PRI port provides digital trunk connectivity to legacy telephone systems, ISDN networks, or carrier services. Combined with the FXS ports and DSP resources, it allows the SBC 1000 to consolidate multiple telephony interfaces into a unified SIP gateway.
How do the DSP resources support voice processing?
The 2 medium DSP resources handle real-time codec conversion, echo cancellation, and voice quality optimization. This enables seamless communication between analog and digital voice systems while maintaining call quality across protocol conversions.
