Enable or prevent transferring calls from Outlook Voice Access in Exchange Server
Applies to: Exchange Server 2013, Exchange Server 2016
You can enable Outlook Voice Access users to transfer calls to a user who's associated with a Unified Messaging (UM) dial plan, or prevent them from doing so. By default, both this option and the Leave voice messages without ringing a user's phone option are enabled, so that Outlook Voice Access users can transfer calls to users in the same UM dial plan and leave voice messages for them. This setting only applies to Outlook Voice Access users who have entered their PIN and are authenticated.
For additional tasks related to UM dial plans, see UM dial plan procedures in Exchange Server.
