Use the Dial Codes tab to configure the dial codes for a Unified Messaging (UM) dial plan. Several dial code settings can be configured on the dial plan. These include incoming and outgoing calling options.

  • Outside line access code

    • Use this field to type the number or numbers that are used to access an outside telephone number for outgoing external calls. This number will be prepended to the telephone number that is dialed. This is also called a trunk access code. This field will accept 1-16 digits.

    • For many organizations, this number is 9. By default, this field is not populated.

    • Frequently, this setting is used in telephony environments where a PBX is located onsite or maintained in an organization. It may not have to be configured if your organization's telephony environment is maintained by an external business or vendor.

  • International access code

    • Use this field to type the number code that is used to access international telephone numbers for outgoing calls. This number will be prepended to the telephone number that is dialed. By default, this field is not populated. This field will accept 1-4 digits.

    • For example, the international access code for the United States is 011; for Europe, it is 00.

  • National number prefix

    • Use this field to type the number code that is used to dial telephone numbers that are out of an area code but within the country/region. This number will be prepended to the telephone number that is dialed. By default, this field is not populated. This field will accept 1-4 digits

    • For example, 0 is used in Europe and 1 is used in North America.

  • Country/region code

    • Use this field to type the country/region code number that is to be used for outgoing calls. This number will be prepended to the telephone number that is dialed. By default, this field is not populated. This field will accept 1-4 digits.

    • For example, in the United States the country/region code is 1. In the United Kingdom it is 44.

  • In-country/region number format

    • Use this field to specify how a user's telephone number should be dialed by the UM Server in a different dial plan, but having the same country code. This is used by an auto attendant and when an Outlook Voice Access subscriber searches and tries to call the user in the directory.

    • This entry consists of a number prefix and n number of x characters (for example, 020xxxxxxx).

    • To determine the telphone number, UM will append the last n-digits from the telephone number that is specified in the directory to the prefix that is specified.

  • International number format

    • Use this field to specify how a user's telephone number should be dialed by the UM Server in a different dial plan, but having a different country code. This is used by an auto attendant and when an Outlook Voice Access subscriber searches and tries to call the user in the directory.

    • This entry consists of a number prefix and n number of x characters (for example, 4420xxxxxxx).

    • To determine the telphone number, UM will append the last n-digits from the telephone number that is specified in the directory to the prefix that is specified.
