Routing elements150 System functions and features as of R3.0syd-0367/1.3 – R3.0 – 03.20135. 7. 3 User Groups for Voice Mail and Other ApplicationsUser group 17 (Aastra 415/430) and user group 25 (Aastra 470) have been designedto accommodate a voice mail server.User groups 18 to 21 (Aastra 415/430) or 26 to 29 (Aastra 470) are provided for ap-plications that require a call forwarding to a user group.These user groups differ from ordinary user groups in the following way:• In the case of calls to these user groups, redirections of the UG user are not car-ried out. However, callers who dial the user in the user group directly are redi-rected.• They can be the destination of a Call Forwarding Unconditional or Call Forward-ing on No Reply, even if the diverting user is still a member of a different usergroup. In each case redirections to these user groups due to Call Forwarding willbe carried out only once the call forwarding time has elapsed.• It is not possible to divert these UG users to the special user groups. This applieseven if the user logs out of the UG beforehand.• Only the user group element "Member group" is available.• Global call distribution is not available.• It is possible to configure whether or not calls should generate an entry in thelist of unanswered calls for the corresponding user whenever calls are divertedto these user groups (see Tab. 219).The following applies in particular for the voice mail user group:• Up to 16 voice channels (= user-group members) can be implemented for eachuser group.• If the voice mail user groupis not taken up by a voice mail application, it can beused for other applications.
