[cisco-voip] CUBE across VRFs

Only one voice vrf can be defined in IOS. Global under voice service voip.

Cube-SP lets you do multiple vrf's but is EoL and way different configuration. 

If you plop a cube off your router and router interface is in a vrf and your separate cube is on that network then it should be fine as the cube is just a host then .... with default route to router.

This idea is no connectivity between them, other than the application-layer connectivity provided by CUBE. This is hypothetical – I’m just trying to understand how/if this would work. I’m looking to plop a CUBE between my network and a SIP provider’s network without having to participate in routing protocol on either side.

I’ve never used it, but I’m envisioning an ISR having a VRF-Lite with default route pointed at my network, and a VRF-Lite with default route pointed at the SIP provider’s network. I’m thinking this would be the preferred way to do it, but maybe I’m missing something?
