Overall Satisfaction with Cisco Unified Border Element (CUBE)

We use Cisco Unified Border Element (CUBE) as a virtual SBC to connect our SIP provider with Microsoft Teams Direct Routing. It ensures secure TLS communication, flexible SIP routing, and compatibility between systems. Cisco Unified Border Element (CUBE) gives us reliability, control, and scalability while supporting our hybrid voice environmen connecting the branches to the main office.

Pros

  • Microsoft Teams Direct Routing
  • SIP configurations
  • Voice Security over network

Cons

  • totally CLI (command line interface)
  • troubleshooting steps
  • required especific knowledge to implements
  • Migration to Ms Teams Direct Routing
  • Less hardware phones
  • Define a company standard for voice comunication
I rated Cisco Unified Border Element’s (CUBE) usability an 9 out of 10. It offers excellent flexibility, reliability, and integration with Microsoft Teams Direct Routing. However, its configuration can be complex for non-experts. Once properly implemented, it provides powerful SIP control, security, and scalability in both virtual and hybrid voice environments that we require.
  • Cisco Unified Communications Manager (Call Manager)
Cisco Unified Border Element (CUBE) complements Cisco Unified Communications Manager by acting as a secure SIP gateway for external connectivity. While CUCM manages internal call control, because we need to mantain some hardware phone, Cisco Unified Border Element (CUBE) enables Direct Routing with Microsoft Teams. We selected Cisco Unified Border Element (CUBE) for its flexibility, TLS encryption, SIP normalization, and ability to bridge cloud and on-premises voice systems efficientlly.

Microsoft Teams, Cisco Unified Communications Manager (Call Manager), Cisco Meraki MX
Cisco Unified Border Element (CUBE) is ideal for secure SIP integration between Microsoft Teams Direct Routing, SIP carriers, and Cisco UC systems. It offers flexibility, encryption, and advanced routing. Maybe less appropriate for small businesses or non-SIP systems, as it requires technical expertise and ongoing management for configuration, certificates, and monitoring to have the best working solution.
