Cisco Voice Gateway Require CUBE to configure SIP Trunk

[dvaggalis]

Can a SIP trunk be configured on a Cisco Voice Gateway without enabling CUBE or require CUBE licensing?

[Mohammed al Baqari]

CUBE license isn't required to enable cube function. The functionality will
work even without the license. Also sip trunk on voice gateway isn't cube.
Cube is ip to ip (not ip to pstn)

I understand that CUBE licensing is the honor system, and is not actually applied to the Gateway.  I'm asking if I need to enable CUBE or can I just create a SIP connection on the Voice Gateway, connecting to a Service Provider, another CUCM Node, a 3rd Party IP/PBX, etc...

I understand this is not "Best Practice" just curious if this is technically possible and that it also doesn't get you in licensing trouble with Cisco.

Yes it will work.

From a legal/licensing POV, you do need to buy the CUBE licenses for your GW if you intend to use it as a CUBE.

But can't I configure SIP without enabling CUBE?

@Mohammed al Baqari has already replied to you on this; CUBE is only needed when you have IP to IP connectivity needs. If you have a SIP trunk to CUCM on the one call leg and the other call leg is a connection to the PSTN through, for example, an ISDN PRI then you do not need have CUBE enabled.
