• Click the Create button.

Supported Products

On-Call Optimizer’s ICS support is compliant with the RFC 5545 specification and should work with any calendar product producing a valid iCalendar feed in this format. On-Call Optimizer has been specifically tested with ICS feeds generated by the following products:

• Google Calendar
• Microsoft Outlook

Recurring Events

On-Call Optimizer supports expanstion of recurring events defined using the RRULE attribute in ICS feeds.

• Recurring events are automatically expanded and processed as individual event occurrences in later availability and assignment processes.
• Occurrences are expanded within the same 90-day availability window used for all calendar imports. Occurrences beyond this window are not processed.
• A maximum of 100 occurrences per recurring event are processed. Events with very high-frequency recurrence rules (e.g. every minute) will be capped.
• If a recurring event cannot be expanded (e.g. due to a malformed RRULE), the original event instance is used as a fallback.
• Full day events are imported as the full day in the timezone of the schedule as specified in the feed itself.

Required Permissions and Data
