Adds the ability to Android to initiate a 2 Digit Call.

Over here the phone number to the switch-board is "99". Trying
to call "99" on an Android device dont work as expected (it
works on other devices though).

Exception (1) to Call initiation is:
  If the user of the device is already in a call and enters a
  Short String without any #-key at the end and the length of
  the Short String is equal or less than 2 the phone shall
  initiate a USSD/SS commands.

Exception (2) to Call initiation is:
  If the user of the device enters one digit followed by the
  #-key. This rule defines this String as the "#-String" which
  is a USSD/SS command. The phone shall initiate a USSD/SS
  commands.
