Permission settings allow administrators to define which features the extension can use. The permissions to jump into calls and listen to conversations may be legally restricted in certain countries, so use extra caution here. The permission to override DND is useful for assistant extensions that are responsible for screening calls.

Note: When entering extensions in this section, use a space as a separator if specifying multiple extensions. You may use wildcards, for example, an asterisk (*), to match all extensions of the domain.

Administration Permissions

• Domain Administrator: The permission to manage the domain should be given only to those who are allowed to change passwords, create or delete accounts, change dial plans and rates, and so forth.

Call Permissions

• Barge into calls of the following extensions: Call Barge-in allows a third party to barge into an in-process call. Typically, this third person is either a secretary contacting the boss or possibly a co-worker in the next cube who needs help on a call. The permissions to jump into calls and listen to conversations may be legally restricted in certain countries; please use extra caution here. Once permission has been set, Call Barge-in can be activated using the *81 star code.

• Teaching (whisper mode) for the following extensions: Call Teach mode allows a third party on a line with only one of the parties knowing. This is typically useful in a call center when a trainer wants to offer tips to a new agent without the customer knowing. Once permission has been set, Call Teach can be activated using the *82 star code.

• Listen in on calls of the following extensions: In Listen-In mode, a third party can listen in without being detected. The two parties speaking to each other are not aware of the listen-in. Users with permission to use Listen-in can activate it using the *83 star code.

• Call the following extensions even if DND is set: If this flag is set, the account will be permitted to call the extension indicated in this field, even if that extension is currently on DND. This applies only to DND which has been set on the system. The permission to override DND is useful for extensions being used by assistants who are responsible for screening calls.

• Intercom to the following extensions: This feature is used for communicating with one other person. The two parties must each have their own extension number. (Intercom will not work between two phones that are registered to the same extension.) Users with permission to intercom can activate it using the *90 star code.

• Domain accounts that can be put into night mode: This feature enables users to forward domain accounts (e.g., auto attendant, hunt group, etc.) to their own extension. Domain accounts that are entered into this field can be put into night mode by this user. Star code *80 is used to activate this feature.

• May clean up the following extensions: This feature enables an extension to clean up other extensions and is useful in a hotel implementation where voicemail must be cleaned out and greetings reset. Star code *84 is used to activate this feature.

• Only the following extensions may call this extension: This feature can be used to limit the users who can call another user’s extension.
