Dial rules determine how local users can respond to messages from callers. You can apply different rules to remote users and to callers who are not members of your organization. For example, local users may be able to return a call from a remote user by replying to a call answer message, but local users must dial the telephone number of the other caller.
Your local Messaging system needs to identify remote users so that the Messaging system can apply dial rules correctly and retrieve directory information about the user. Dial-out rules define the dial strings that are sent to the telephony server for making calls.
The dial rules are used for the following features:
