Problem

In Dynamics 365 Contact Center, agent capacity is only blocked after an inbound call is accepted, not when the call notification (ringing) is sent.

This creates a risk scenario:

• An inbound call is offered to Agent 1 (ringing, not yet accepted)
• Agent 1 is still shown as Available
• Another agent initiates a consult or transfer to Agent 1
• Agent 1 receives the customer call and the consult/transfer simultaneously

Risk / Impact

• Unintended concurrent interactions on a single agent
• Degraded call quality and agent experience
• Operational errors during peak volumes
• Increased handling time and risk of customer confusion

This behavior is particularly critical in contact centers with frequent consults and transfers.

Proposed improvement

Provide an option to reserve / block agent capacity as soon as an inbound call is offered, until the call is accepted, declined, or times out.

This could be implemented via:

• A configurable setting at workstream or capacity profile level, or
• An intermediate presence state (e.g. Ringing / Reserved)

Business value

• Prevents conflicting interactions
• Reduces operational risk
• Aligns capacity handling with real-world contact center expectations
