Hi,

i have a situation in my application to accept a 9 digit SSN number from the caller. But the VXML behavior is inconsistent meaning first time entry fails, second time entry also fails to understand the & then after retrying for the third time on entering the same number it accepts. The scenario with the PLUM generated log file is as below:

For your reference, the DNIS number is - 9308

The IVR asks to enter a 9 digit SSN number & on entering the 9 digit number for the 2 consecutive times the behavior in the log file is as follows:

I m confused with this behavior of PLUM. Please help me.

Hi,

The long list of "Loading Builtin grammar" messages makes us think you probably have some sort of IVR grammar scoping/precedence problem, but we can't help without seeing the actual VXML script.

Regards,

Plum Support

Here is the VXML we are using...

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
<var name="ssn_number" />  
<var name="dobset" />
<var name="submitcount" expr="1" />
<form id="prompt_ssn_number">
    <field name="MyField" type="digits?length=9">

      <prompt><voice name="crystal">        
         <break size="medium" /> 
Please Speak or Key your Social Security Number Now</voice></prompt>
      
      <filled>
        <assign name="document.ssn_number" expr="MyField" />
        <goto next="#confirm_ssn_number" />
      </filled>

    </field>
  </form>

  <form id="confirm_ssn_number">
    
    <block>
     <prompt><voice name="crystal">
        <break size="medium" />The Number you entered is<break size="medium" />
         <say-as type="acronym"><value expr="ssn_number" /></say-as>
     </voice></prompt>
    </block>
    
    <field name="ssn" type="digits?length=1">
      <prompt><voice name="crystal">
        <break size="medium" />Press or Say 1 if this is correct? <break size="medium" />
           Press or Say 2  to Re enter
       </voice></prompt>
    </field>
    
    <filled>
      <if cond="ssn=='1'">
        <goto next="#prompt_dob" />
        <elseif cond="ssn=='2'" />
        <goto next="#prompt_ssn_number" />
      </if>
    </filled>
 
   </form>
 </vxml>

Hi,

We ran this snippet of IVR code and did not experience any nomatch errors over the course of 8 attempts (4 using keypad, 4 using voice).

As we've mentioned previously, if you are dialing internationally and/or using a VOIP phone, you are simply going to experience problems with both speech and dtmf input.

Hi,

We are unsure about the availability of DTMF IC's being manufactured, but I'm sure if you Google searched on this topic, you could find some information such as this:
