Explanation

When Cisco Unity Connection is integrated with Cisco Unified CM via a SIP trunk, music on hold (MoH) is not available (C) during supervised transfers. This is a known limitation of the SIP trunk integration type. Unity Connection's SIP trunk integration does not support the signaling necessary for CUCM to inject a MoH stream during hold states within a supervised transfer flow. An MTP resource (A) cannot resolve this limitation. Using only the default MoH source (B) or multicast MoH (D) are also not viable because the fundamental feature is unsupported in this integration model.
