Last external number redial

When you initiate an external call the system automatically stores all
the dialled digits, irrespective of whether the call was successful or
not. Stored numbers can consist of maximum 31 digits.
Note: To redial a number that incorporates a wait for a new
dial tone, you must indicate to the telephone where in the
number it must pause and wait for the new dial tone. To do
this, press the redial-key at the proper place in the number.
