• Endpoints must be migrated to Webex before the Unified CM servers are decommissioned. in context
• Cisco recommends starting with the Control Hub Migration Insights tool, which analyses Unified CM TAR exports and CDR data to report device eligibility, feature usage, shared lines and hunt groups. in context
• Cisco recommends moving users in groups and keeping users with dependencies (BLF monitoring, hunt groups, shared lines, call pickup groups) in the same group. in context
• Webex Calling voicemail is built in and cannot integrate with premises voicemail such as Unity Connection. in context
• There is no native way to migrate existing Unity Connection voicemail messages or greetings to Webex Calling. in context
• A Control Hub location can be assigned only one PSTN option: Cisco Calling Plans, Cloud Connected PSTN, or premises-based PSTN through a Local Gateway. in context
• All users, whether or not they have moved calling platform yet, should be provisioned in Webex at or before the start of the project, which also enables directory search across migrated and non-migrated users. in context
