Range: 1 to 20 characters (valid characters are 0 through 9, '-', ',', '/', '*', '#', and 'P'). The characters '-', ',', and '/' are allowed only for ease of reading. They are not sent to the remote port. The 'P' character is used to indicate a pause is required in the playout of the digits at the remote end.
