SBCs that Squarely Outperform the Competition
Ribbon SBCs are a Better Choice
Many Cisco customers are familiar with their existing choices for SBC solutions. Ribbon SBCs offer more capabilities and better value for Local Gateway deployments.
Ribbon advantages
1. Ribbon SBCs offer greater scale
- Branch offices (under 100 concurrent calls)
- Regional offices (1000 and under concurrent calls)
- HQ (up to 150,000 concurrent calls)
2. Flexible deployment models:
- Hardware appliances (with multiple legacy interface options)
- Multiple virtual environments (multiple hypervisors)
- Private & public cloud (Azure, AWS, and GCP)
3. Broad interoperability for deployment in heterogeneous environments
- Assures investment protection for future communication choice
4. Proven carrier-grade security and performance
5. The same solution also protects premises or cloud contact centers

Get Connected to Webex Calling
Ribbon SBCs Make it Easy to Move 1 or 10,000 Users
- Acquire a Webex Calling license or Cisco Collaboration Flex Plan license.
- Pick a telecom provider (use existing or new). The telecom provider’s SIP trunks will be delivered to a Ribbon SBC deployed in the organization’s office, data center, or in the cloud. A special Webex-certified provider is not required – the Ribbon SBC assures interoperability.
- Ribbon’s Session Border Controller will terminate the SIP trunks and pass the calls to the Webex Cloud or a local PBX (such as a Cisco CUCM) or both.
- The SBC acts as a secure voice firewall, mitigates SIP interoperability issues, and manages media connectivity. Most of Ribbon’s SBCs are Webex Local Gateway certified (see chart below).
What is the SBC’s Role in Webex Local Gateway?
Webex requires a Webex-certified SBC to act as a bridge between the Webex Cloud, a premises phone system (such as a Cisco CUCM), and an organization’s telecom provider. The session border controller provides multiple functions:
- Security – it acts as a voice-aware firewall, protecting the voice traffic itself and it prevents bad actors from entering the data network via the voice network.
- Interoperability – Ribbon’s SBCs can adjust key deployment parameters to best match the telecom provider’s requirements, the Webex Cloud’s requirements, and a premises phone system's requirements. All the pieces connect and work!
- Legacy Connectivity – many organizations still have analog, BRI, or PRI-based trunk ports, analog phones, elevator phones, door phones, and fax machines. Ribbon’s hardware-based SBCs have analog & digital ports (FXS and FXO) to keep these assets connected and available.
- CUCM Migration – organizations may have technical or business requirements that require the Cisco CUCM (or other PBXs) to stay connected for an extended period. Ribbon SBCs can provide SIP forking and simultaneous ringing so that both Cisco Webex and the legacy PBX share connectivity.
- Resiliency or Failover – Ribbon SBCs have multiple options to manage disruptions in service depending on the deployment model. These tools can keep your organization connected even if the unexpected happens.

Protect Your Network from Communication Threats
Certificate-based Authentication Offers Better Performance
Ribbon SBCs deployed as Webex Local Gateways rely on modern Certificate-based Authentication (CBA) rather than more traditional SIP registrations. CBA uses a digital certificate, acquired via cryptography, to identify the user (or device), granting access to a network or communications application. This security model:
- Eliminates fixed devices with generic passwords
- Digital certificates are installed centrally, enables end-to-end encryption
- Eliminates end user engagement (or lack thereof)
- Covers all endpoints types
- Mutual authentication
Using Certificate-based Authentication also eliminates potential SIP registration storms, making Ribbon solutions a better choice for larger, multi-site deployments.
