Call Answering Rules is a new feature in Microsoft Exchange Server 2010. Using this feature, end users can dictate how their incoming call answering calls should be handled. Call answering rules are applied to incoming calls similar to the way Inbox rules are applied to incoming e-mail messages.
Call answering rules are stored in the mailboxes of users who are enabled for Exchange 2010 Unified Messaging. Nine call answering rules can be set up for each mailbox. These rules are independent of the Inbox rules that are set up by users and don't consume a part of the Inbox rules quota for the user. By default, no call answering rules are configured. If an incoming call is answered by a Unified Messaging (UM) server, the caller can be prompted to leave a voice message or if the caller doesn't prompt the system, the caller will also be able to leave a voice message for the called party.
A call answering rule consists of two parts: conditions and actions. You can associate one or more conditions with a single call answering rule. The call answering rule will only be processed if all the conditions for the rule are met. You can also associate one or more actions with a single call answering rule. These actions determine what options will be offered to the caller when the call answering rule is processed.
Call Answering Rules support the following conditions:
Who the incoming call is from
The time of day
Calendar free/busy status
Whether automatic replies are turned on for e-mail
The following actions are supported:
Transfer the caller to someone else.
Leave a voice message
|If a user records a custom greeting for a call answering rule, they must include the menu option as part of the custom greeting when they configure the call answering rule. If they don't, the Unified Messaging server won't generate a menu prompt that lets the caller know what his or her choices are. After UM plays the custom greeting, the server will wait for the caller's input. If the menu option isn't included in the greeting, the caller won't input anything and the server will prompt them, asking "Are you still there?"|
For more information on the conditions and actions, see Call Answering Rules for the End User.
As shown in the following diagram, when an incoming call is received for a UM-enabled user, UM will:
Determine whether the user has created any call answering rules. If not, UM will offer the caller the option of leaving a voice message.
If one or more call answering rules have been configured, UM will evaluate each of these rules. The first rule whose conditions are met will be processed.
After evaluating all the rules, if UM doesn't find a rule whose conditions are met, UM will ask the caller to leave a voice message.
Depending on how a call answering rule is configured, an incoming call may result in a call transfer. When this happens, the transfer target phone number will be subject to the dialing rules and restrictions on the UM mailbox policy that the called party is associated with. For more information about outdialing and dialing rules and restrictions, see the following topics:
- Configure Dialing Rule Groups on a UM Dial Plan
- Create a Dialing Rule Entry on a UM Dial Plan
- Enable Dialing Restrictions on a UM Mailbox Policy
By default, call answering rules are automatically enabled for UM-enabled users. However, you can disable call answering rules for users by disabling the feature on a UM dial plan, a UM mailbox policy, or the user's mailbox. For details about how to enable or disable call answering rules, see the following topics:
- Allow or Prevent Call Answering Rules on a UM Dial Plan
- Enable or Disable Call Answering Rules on a UM Mailbox Policy
- Enable or Disable Call Answering Rules for a UM-Enabled User
Important: Call answering rules aren't available for UM-enabled users who have a mailbox on a Microsoft Exchange Server 2007 Mailbox server.
