A. B. C. D. E.A.
When installed on the same server there is no way to create trunk that is why sccp is the only way Cisco Unity Connection and Cisco Unified Communications Manager are installed on the same server.
When Cisco Unity Connection and Cisco Unified Communications Manager (CUCM) are installed on the same server as Cisco Unified Communications Manager Business Edition (CUCMBE), the integration method that is supported depends on the version of CUCMBE.
In CUCMBE version 9.x and later, both SCCP and SIP integrations are supported, but you must choose one or the other. SCCP is a Cisco proprietary protocol that is used to control Cisco IP phones, while SIP is an industry standard protocol used for voice and video communication.
In the case of SCCP integration, Cisco Unity Connection communicates with CUCM using the SCCP protocol to control the Cisco IP phones. The SCCP integration requires that the Cisco IP phones be registered to the CUCM.
In the case of SIP integration, Cisco Unity Connection communicates with CUCM using the SIP protocol to control the Cisco IP phones. The SIP integration requires that the Cisco IP phones be registered to the CUCM.
Q-Sig integration is not supported when Cisco Unity Connection and CUCM are installed on the same server as CUCMBE. If Q-Sig integration is required, it can be achieved through a voice-enabled Cisco ISR router.
Circuit-switched integration through PIM is not supported when Cisco Unity Connection and CUCM are installed on the same server as CUCMBE.
Therefore, the correct answer to the question is C: both SCCP or SIP integration are supported, but you must choose one or the other.
