Log in

Configure CUBE functionality on a device by creating a Cisco IOS XE Catalyst SD-WAN device CLI template or CLI add-on feature template.

This task guides you on how to configure CUBE functionality on a device.

CUBE (Cisco Unified Border Element) enables devices to process voice and video traffic with proper call routing and media handling capabilities.

Before you begin

Create a Cisco IOS XE Catalyst SD-WAN device CLI template or a CLI add-on feature template for the device to use the CUBE functionality

Follow these steps to configure CUBE:

Procedure

Create a Cisco IOS XE Catalyst SD-WAN device CLI template or a CLI add-on feature template for the device to use the CUBE functionality

Example:

The following example shows a basic CUBE configuration using a CLI add-on template:

voice service voip
 ip address trusted list
  ipv4 10.0.0.0.255.0.0.0
  ipv6 2001:DB8:0:ABCD::1/48
  !
 allow-connections sip to sip
 sip
  no call service stop
  !
dial-peer voice 100 voip
  description Inbound LAN side dial-peer
  session protocol sipv2
  incoming called number .T
  voice-class codec 1
  dtmf-relay rtp-nte
  !
 dial-peer voice 101 voip
  description Outbound LAN side dial-peer
  destination pattern [2-9].........
  session protocol sipv2
  session target ipv4:10.10.10.1
  voice-class codec 1
  dtmf-relay rtp-nte
  !
 dial-peer voice 200 voip
  description Inbound WAN side dial-peer
  session protocol sipv2
  incoming called-number .T
  voice-class codec 1
  dtmf-relay rtp-nte
  !
 dial-peer voice 201 voip
  description Outbound WAN side dial-peer
  destination pattern [2-9].........
  session protocol sipv2
  session target ipv4:20.20.20.1
  voice-class codec 1
  dtmf-relay rtp-nte

For information about device CLI templates and CLI add-on templates, refer to the Cisco Catalyst SD-WAN Control Components and Device Management Guide.

For information about CUBE configuration and usage, refer to the Cisco Unified Border Element Configuration Guide.

For information about the CUBE commands that Cisco Catalyst SD-WAN supports for use in a CLI template, refer to CUBE commands .

After successfully applying the configuration, the device is enabled to function as a Cisco Unified Border Element, processing voice and video traffic according to the defined dial-peers and voice service settings.

What to do next

After configuring CUBE, you should verify the voice service and dial-peer configurations to ensure proper call routing and media handling. You can also integrate the CUBE-enabled device with your Cisco Unified Communications Manager or other call control applications. For more information, refer to Verify CUBE on the Device.
