Setting the Called/Calling Party Type on a Per Call Basis

You can set the called/calling party numbering type and plan on a per call basis using the following instructions.

Modify the Dial Plan to create dial strings with this character sequence at the beginning of the string: !Xyxy.

• The ‘!’ indicates that the next four characters are going to be used to set the Called Party Number Type and Plan as well as the Calling Party Number Type and Plan.

• The X (first character) is the Called Party Number Type. Valid Values are:
  
  U = "Unknown"
  
  I = "International"
  
  N = "National"

• The y (second character) is the Called Party Numbering Plan. Valid Values are:
  
  U = "Unknown"
  
  E = "E.164"
  
  T = “Telephony Numbering Plan”

• The x (Third character) is the Calling Party Number Type. Valid Values are:
  
  U = "Unknown"
  
  I = "International"
  
  N = "National"

• y (Fourth character) is the Calling Party Numbering Plan. Valid Values are:
  
  U = "Unknown"
  
  E = "E.164"
  
  T = “Telephony Numbering Plan”

Example: The Default Dial String format "!NENE{1}{2}{3}{4}{5}{6}{7}{8}­{9}{10}{11}{12}{13}" is set the Called Party Number Type to National, the Called Party Numbering Plan is set to E.164, the Calling Party Number Type is set to National, and the Calling Party Numbering Plan is set to E.164.
