sample VXML ivr application which get input from user and play caller entered number.

below code working fine, but when i remove grammer tag, it playing some error code, i am not able to track that error code.

now i want to make little change, that user can enter more than one number.

exactly caller have to enter their their mobile number.

how to change the code to accept multiple number.

<?php
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
?>
<vxml version = "2.1">
      <meta name="maintainer" content="your_email_address@wherever.com"/>
    <form id="guessNumber">
        <field name="guess">
          <grammar type="text/gsl">
            [dtmf-1 dtmf-2 dtmf-3 dtmf-4 dtmf-5 dtmf-6 dtmf-6 dtmf-7 dtmf-8 dtmf-9]
          </grammar>
          <prompt>
            <prosody rate="slow">
Guess what the computer is thinking! Pick a number between 0 and 9.
            </prosody>
          </prompt>
          <nomatch>
            <prompt>
              <prosody rate="slow">
Is that a number? Please try again.
              </prosody>
            </prompt>
            <reprompt/>
          </nomatch>
          <filled>
            <prompt>
              <prosody rate="slow">
you said
                <value expr="guess"/>
                !
              </prosody>
            </prompt>
          </filled>
        </field>
      </form>
      </vxml>

Answer 1

This question is a little old, but for future readers...

It is hard to tell what you are asking. To allow more than one digit, change the grammar to:

<grammar version="1.0" xml:lang="en-US" root="keypress" 
         mode="dtmf" scope="document">
    <rule id="keypress" scope = "public">
      <one-of>
          <item> 1 </item>
          <item> 2 </item>
          <item> 3 </item>
          <item> 4 </item>
          <item> 5 </item>
          <item> 6 </item>
          <item> 7 </item>
          <item> 8 </item>
          <item> 9 </item>
          <item> 0 </item>
      </one-of>
    </rule>
</grammar>

Then specify the number of digits using:

<field name="guess" type="digits?length=2" >

If however, you are asking how to get multiple responses from the caller just add a second field element to the form like this:

<form id="guessNumber">
    <field name="guess1" type="digits?length=1" >
        <prompt>
            Guess what the computer is thinking! Pick a number between 0 and 9.
        </prompt>
    </field>

    <field name="guess2" type="digits?length=1" >
        <prompt>
            Guess what the computer is thinking now! Pick a number between 0 and 9.
        </prompt>
        <filled>
            You guessed <value expr="guess1"> and <value expr="guess2">.
        </filled>
    </field>
</form>

nomatch and prosody elements removed them for clarity. They can be added back in.
