The scenario describes an issue where Message Waiting Indicators (MWIs) aren't lighting up for SIP-integrated Cisco Unity Connection users, even though calls reach voicemail. This points towards a configuration problem with MWI notifications on Cisco UCM.

• A. Modify the SIP Trunk Security Profile on Cisco UCM: While SIP trunk security is important, it likely wouldn't affect MWI functionality in this case.
• B. Increase the Delay Between Requests timer on Cisco Unity Connection: This setting might be used for other purposes but wouldn't directly address MWI notification issues on Cisco UCM.
• C. Assign a Calling Search Space to the SIP Trunk on Cisco UCM: Calling Search Space defines call routing, not MWI notification.

The Cisco XCP XMPP Federation Connection Manager service on the IM & Presence node depends on the Cisco XCP Router service. If the XMPP Federation Connection Manager fails to start, a likely cause is an issue with the XCP Router.

"When Unity Connection receives a call, it first determines if it is a direct or forwarded call based on the call information that is sent by the phone system, and then applies the applicable call routing table. If the call information matches all of the conditions for the first rule, the call is routed as specified in the rule. If any of the conditions specified in the first rule are not met, the call information is then compared to the conditions of the second rule, and so on, until a rule is found that matches all the characteristics of the call." https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/administration/guide/10xcucsagx/10xcucsag080.html#pgfId-1129913
