You configured a Cisco ISR G2 as a SIP gateway, but the gateway does not show that it is registered with Cisco Unified Communications Manager.
What is causing this issue?
A. Cisco Unified Communications Manager does not support SIP gateways.
B. The gateway does not have the UC license installed.
C. The gateway does not have Cisco Unified Border Element session licensing.
D. Cisco Unified Communications Manager does not show a SIP gateway as registered if it is not properly configured.
E. Cisco Unified Communications Manager never shows a SIP gateway as registered even when it is properly configured.
F. The Cisco ISR G2 cannot be a SIP gateway.

I believe it is A.
CUCM connects to SIP gateways (e.g. CUBE or any other SBC) through a SIP trunk.
Thats not the question.
it’s functioning as a gateway, so it’s sip gateway. It is D
