Internal Dialing - Cisco UC320W Administration Manual

Internal Dialing

Use the Configuration > Telephony > Internal Dialing
page to configure the internal extension format, the
system extensions, and the functions of dialed digits.
For example, specify which digits are used in extension
numbers, which digits are pressed for an outside line,
and so on.
Note: The external dial plan is determined by your
regional settings (see the Region page). The external
dial plan encompasses settings such as the required
length of a dialed phone number (7 digits or 10 digits,
for example) and the call processing tones that are
used.
Extension Length
For Extension Length, specify the length of the internal extension numbers: 2 digits, 3 digits, or 4 digits.
To choose the digits that can start each range of extension numbers, see the Meaning of First Digit
Dialed section of this page.
Allowed Dial Patterns
Choose the function that you want to assign to each digit. After you make a selection, the Dial Pattern
field displays an example. For Extensions, the Utilization field displays the number of possible
assignments. For example, with the two-digit extension length, each selected digit can support up to 10
extensions.
Note: Assign at least one digit to each of the following dial patterns: Extensions, Voicemail Prefix, and
Reserved. In PBX or Blend mode, also assign at least one digit to Outside Line. More information is
provided below.
• Dial Immediately: The digit can be used as a one-digit extension number. For example, the
default configuration allows 0 to be used for this purpose, and assigns 0 as the Auto Attendant
extension number. Another option might be to assign another extension number to the Auto
Attendant and assign 0 to a user, such as your receptionist. Note: If a digit is assigned to this
function, it cannot be used as a personal speed dial digit.
• Extensions: The digit is used as the first digit of an internal extension number. For example, if
you assign this function to the digit 2, and your extension length is three digits, you will be able
to configure extensions such as 200, 201, 202, and so on. At least one digit must be assigned to
this function, to support extension numbering.
• Voicemail Prefix: The digit is used to dial a voicemail box. For example, if this digit is 7, and a
voicemail box is 201, then you can press 7201 to leave a message in this mailbox. At least one
digit must be assigned to this function, to support voicemail access.
• Outside Line: The digit is used to place an outbound call. For example, you can press 9 to get
an outside line. Not applicable when the system is in Key System mode. In PBX or Blend mode,
at least one digit must be assigned to this function, to support outbound call routing. Note: If a
digit is assigned to this function, it cannot be used as a personal speed dial digit.
Tip: In PBX mode or Blend mode, if you have FXO trunks and SIP/BRI trunks, you might want to enable
more than one digit to get an outside line. Then on the Outbound Trunks page you can assign a different
digit to each trunk. For example, users could then press 8 for the FXO trunk and press 9 for the SIP/BRI
trunk.
• Not Allowed: The digit is not allowed as the first digit in a dialing sequence. If a user presses the
digit to initiate a call, an error tone is played.
• Reserved: This digit supports system functions. One digit must be assigned to this function.
Extensions for System Features
For each system feature, keep the default settings, or enter an extension number in the box. Extension
numbers must be unique and must comply with dial plan settings on this page. An error message
appears if you enter an invalid or duplicate extension number. Tip: A quick way to enter a valid
extension number is to click the phone icon next to the extension number field.
