Request to make a voice call.

The purpose of the P dial modifier is to signal the 7400B Plus to
dial the number that follows as a voice call. When entered
immediately after the D in a dial command and/or as the first
character in a stored number, the 7400B Plus will place a voice
call. When the P is omitted or the T is used, the 7400B Plus will
place a data call. When the P is entered after the D and a stored
number is dialed, a voice call is made even if the first character of
a stored number is the T dial modifier. The blind dial register is
used to delay between going off-hook and dialing the first digit.

dial modifier can also be used for voice calls.
