Voicemail provides a number of greetings for groups. One of these is an Out of Hours Greeting. Through IP Office Manageror using a short code a hunt group can be taken in or out of service. When the group is Out of Service, callers are played the group's "Out of Hours" greeting and can then leave a message. Alternatively, if an Out of Service Fallback Group has been configured, callers are passed to that group. Similarly, a group can be taken in or out of Night Service by using Manager, short codes or an associated time profile. When the group is in Night Service, callers are played the group's "Out of Hours" greeting and can then leave a message. Alternatively, if an Out of Hours Fallback Group has been configured, callers are passed to that group.
