Objective

The Do Not Disturb (DND) feature allows you to bar incoming calls whenever you are on a meeting or on another call. On DND mode, incoming calls may be redirected to another number, the voice mailbox, or disconnected, depending on the call controller you use.

This article aims to show you some possible ways to enable or disable DND.

Phones with Multiplatform Firmware

The phones referenced in this article are not Enterprise phones that use a specific call controller. If you would like to compare the two different types of phones, check out Compare & Contrast: Cisco IP MPP Phones & Cisco Unified IP Phones.

MPP phones require either service from an Internet Telephony Service Provider (ITSP) or an IP Private Branch Exchange (PBX) call control server. WebEx Calling, Ring Central, and Verizon are examples of an ITSP. Some examples of IP PBX services that work with Cisco MPP phones include, Asterisk, Centile, and Metaswitch platforms.

These ITSP and IP PBX call controllers are a separate system in which the phone and the call controller communicate with each other to provide services such as call park and voicemail. Since the MPP phones do not use a specific call controller, access and procedures vary.

Each call controller can follow different procedures, so we can't tell you exactly how yours will work. For information and help with your specific voicemail commands, refer to the help sites from the provider you chose. If you have an administrator, you can contact them for details and possible training.

Possible Asterisk Commands

In Asterisk, Do Not Disturb is usually controlled by dialing 78 to turn on the Do Not Disturb mode on the phone. To turn the Do Not Disturb mode off, 79 is usually the default.
