For more information about this PIN, see Reset PIN.
Voicemail: Enabled Voicemail to email	Enabled - Allows a caller to leave a voicemail message. Voicemail to email - Forward voicemail messages to an email address. Select this option and enter the target email address. Note: If this phone number is assigned, the email address of the assigned user will be used to populate this field by default.
Call forwarding: Always Busy No answer	Incoming calls to this number are redirected to another number in the following scenarios: Always - All inbound calls are sent to the selected number immediately. This option effectively overrides the other call forwarding options. Busy - Any inbound calls received while the phone is in use are sent to the selected number. This option cannot be selected with Call waiting. When the line is busy, calls can either wait or be redirected, not both. No Answer - If an inbound call to the number is not answered after 3 rings, the call is sent to the selected number. Selecting a call forwarding option enables a field that captures the number to forward the calls to. Warning: Call forwarding is disabled for phone numbers with the Authorization code functionality enabled.
Call settings
Call waiting	Receive a signal that indicates that someone has called you while you are engaged in another call. This allows you to pick up the new call. This option cannot be selected with Call forwarding - Busy. When the line is busy, calls can either wait or be redirected, not both.
Do not disturb	All calls received for this number are redirected as follows: If voicemail is configured, all calls are sent to the voice messaging service. Otherwise, a busy tone is played to the caller.
CLI (Number to be displayed)	Change the number that is displayed as this phone number's caller ID on outbound calls. Example: Select the occupier's main number from this list to show the main number as the caller ID when this number makes a call. Toggle - Enables or disables CLI. Number to be displayed - The number to use as the caller ID. This drop-down list contains all active essensys phone numbers associated with the same occupier or operator. Tips: If the drop-down list is empty, you may need to activate the phone number that you want to use as this phone number's caller ID. If you also enable Hide caller ID, the caller ID will be hidden regardless of the CLI setting.
Hide caller ID	Hides your outgoing Caller ID when you call another number. If enabled, this overrides any CLI number.
