Image:Iv_063.gif Get Letter Step
This step allows callers to use their telephone keypads to enter a letter instead of a digit. Each time a button is pressed, the Server will speak back one of the letters on the telephone keypad. For example, if the caller presses 2, the Server will say 'A'. If the caller presses 2 again, the Server will say 'B'. This process continues until the caller hears the desired letter, and presses one of the exit keys, Image:Iv_910.gif or Image:Iv_911.gif. The Action Steps for Image:Iv_910.gif or Image:Iv_911.gif can be used to route the application depending on how the user terminated the input. Their exact use depends on the needs of your application. One possible use of the Get Letter step is to enable the caller to spell a word using a loop. One of the action steps, perhaps the Image:Iv_911.gif , could be used to accept the current letter and loop back to the Get Letter step to acquire the next letter. The other action step ( Image:Iv_910.gif ) could be used to indicate the end of the word.

Properties

Variable to receive letter: Specifies the TeleFlow Variable to store the user's selected letter. e.g.: @PENDINGTT

TIMEOUT (ms): The length of time - expressed in milliseconds - for which this step will wait for a touch-tone before following the path of the Time Out action step. Defaults to system variable TeleFlow Variable @TIMEOUT if left blank. (e.g.: 1000 or @MY_TIMEOUT)

Entry Convention: Because the telephone keypad is inconveniently missing the letter 'Q' and the letter 'Z', the entry convention field specifies which keys you want to use for them. (Remember to explain this to your caller when asking them to enter letters using this step) Your options are:

  • Z and Q on the '0' button
  • Z and Q on the 'Q and Z on the seven and nine key respectively


Allowable Input: The Get Letter step can be used to get digits, in a similar manner to the Menu steps. This field provides the following options:

  • Alphabet only
  • Numbers only
  • Both

Alphabet only is the manner in which you will most likely want to use this step. Numbers only causes this function to behave very much like the Image:Iv_050.gif Menu step, in which case, you might as well just use the Menu step. 'Both' is handy for dealing with mixed input, such as Canadian postal codes or mixed serial numbers. When Both is selected, the caller will cycle through the characters letters first, and then the number. e.g.:</b> A,B,C,3

Action Steps

Image:Iv_910.gif Star/Asterisk Touch-Tone: Indicates the path to follow if the Image:Iv_910.gif touch tone was pressed.
Image:Iv_911.gif Pound/Number Touch-Tone: Indicates the path to follow if the Image:Iv_911.gif touch tone was pressed.
Image:Iv_920.gif Time Out: If the caller does not select a letter press a touch tone before time runs out (see TIMEOUT above), this path will be followed.
