Do Not Disturb Overview
Do Not Disturb (DND) provides the following options:
Call Reject—This option specifies that the incoming call gets rejected. Depending on how you configure the DND Incoming Call Alert parameter, the phone may play a beep, or display a flash notification of the call.
- Ringer Off—This option turns off the ringer, but incoming call information gets presented to the device, so that the user can accept the call.
When DND is enabled, all new incoming calls with normal priority honor the DND settings for the device. High-priority calls, such as Cisco Emergency Responder (CER) calls, or calls with Multilevel Precedence and Preemption (MLPP), ring on the device. Also, when you enable DND, the Auto Answer feature gets disabled.
Users can activate Do Not Disturb on the phone in the following ways:
- Feature button
- Cisco Unified Communications Self-Care Portal
You can also enable or disable the feature on a per-phone basis from within Cisco Unified Communications Manager.
When you enable Do Not Disturb, the Cisco Unified IP Phone displays the message "Do Not Disturb is active". Some Cisco Unified IP Phones display DND status icons. For details on how individual phone models use Do Not Disturb, consult the user guide for that particular phone model.
When you activate DND, you can still receive incoming call notifications on the phone as specified by the Incoming Call Alert settings in Cisco Unified Communications Manager Administration, but the phone will not ring, except for high-priority calls (such as Cisco Emergency Responder and MLPP calls). Also, if you enable DND while the phone is ringing, the phone stops ringing.
Do Not Disturb is supported on both SIP and Cisco Skinny Call Control Protocol (SCCP) devices.
SIP phones use the SIP PUBLISH method to signal a DND status change to Cisco Unified Communications Manager. Cisco Unified Communications Manager uses a Remote-cc REFER request to signal a DND status change to the SIP phone.
SCCP phones use SCCP messaging to signal a DND status change to Cisco Unified Communications Manager.
