In the Total CPN Len field, type the total number of digits that Communication Manager must transmit.
Note:
Communication Manager combines the value of the CPN Prefix field with the extension that matches the entry on the NUMBERING - PUBLIC/UNKNOWN FORMAT screen. If the length of the number is longer than the length defined in the Total CPN Len field, Communication Manager deletes the leading digits from the extension until the length of the number is equal to the length defined in the Total CPN Len field.
