Refer to the exhibit. What can you determine from the Cisco Unity Connection configuration?

Unity Connection's own server IP address is set in the platform network configuration, not in the telephony integration page where this IP address appears.

MWI delivery depends on voicemail port configuration and the CUCM integration being active; authentication settings alone do not control whether MWI indicators appear on phones.

When configuring a Unified CM Telephony Integration in Cisco Unity Connection, the administrator enters the IP address of the CUCM publisher or subscriber that Unity Connection will use for call control and voicemail port registration. Because 10.1.1.1 appears in the CUCM integration settings rather than in Unity Connection's own network configuration, it identifies the CUCM server - not the Unity Connection appliance itself.

Voicemail port naming in CUCM is administratively flexible and does not require any specific prefix such as 'PhoneSystem,' though naming conventions vary by organization.
