What’s the difference between Standard and Enhanced CUBE sessions?

Standard sessions cover voice SIP trunk calls. Enhanced sessions add video and advanced media features like T.38 and richer codec handling.

How do I activate a Cisco CUBE Smart License?

Create or use your Smart Account and Virtual Account in CSSM, generate a registration token, configure Smart Licensing Using Policy transport (direct, proxy, or Satellite) on the router, install the token, and verify with show license commands.

Can I register CUBE without direct internet access?

Yes. Use Smart Licensing Using Policy with an on-prem Satellite or export/import workflow to report usage without direct internet connectivity.

Do I need subscription or perpetual licensing for new deployments?

New deployments should align to Smart Licensing and relevant subscriptions (e.g., Flex). Perpetual RTU options are end-of-sale and should be migrated to Smart where possible.

How is High Availability (HA) handled for CUBE licensing?

HA mirrors licensed session capacity on the standby node. Size for busy hour, add headroom, and account for mirroring if you require redundancy.

Cisco CUBE License (Smart Licensing)

CUBE, a software-based session border controller that supports both SIP and H.323 protocols, makes it possible for enterprise VoIP networks and service providers to integrate seamlessly.
