If the system administrator has allowed you, you can change the service state of a group through the Status menu.
To do this during a call, press the PHONE key and then press the Status soft key.
InS (In Service) – The groups operates as normal, distributing calls to available members of the group.
NS (Night Service) – The group is in 'night service' mode. Calls are redirected to its night service fallback destination if set, otherwise to voicemail if available. A hunt group can also be put into and out of night service automatically by the telephone system using a time profile.
OOS (Out of Service) – The group is out of service. Calls are redirected to its out of service fallback destination if set, otherwise to voicemail if available. The phone displays an O when one of the groups of which your are a member is out of service.
TP (Time Profile) – This setting indicates that the group's status is being controlled by a time profile on the telephone system. That time profile sets when the group is in service and in night service. You can override this to put the group into the Out of Service state. You can then use the phone to returns the group to time profile control when required.
