Hi,

I've always a problem with the key pound.

I've this code:

<form id="main">
   <field name="msg">
        
            <property name="inputmodes"        value="dtmf" />
            <property name="termchar"          value="" />
            <property name="interdigittimeout" value="20s" />
            <property name="termtimeout"       value="0s" />
            
            <prompt>
                <audio expr="media_message">
                </audio>
            </prompt>
            
            <grammar root="ROOT" type="application/srgs+xml" mode="dtmf"> 
                <rule id="ROOT" scope="public"> 
                    <one-of> 
                        <item repeat="0-255"> 
                            <ruleref uri="#digit"/> 
                        </item>
                        <item> "#" </item> 
                    </one-of> 
                </rule> 

                <rule id="digit" scope="public"> 
                    <one-of> 
                        <item> 0 </item> 
                        <item> 1 </item> 
                        <item> 2 </item> 
                        <item> 3 </item>

                        <item> 6 </item> 
                        <item> 7 </item> 
                        <item> 8 </item> 
                        <item> 9 </item>            
                        <item> "#" </item>                         
                    </one-of> 
                </rule> 
            </grammar>
            
            <filled>            
                <if cond="msg$.utterance.length > longueur_max">
                    <audio expr="nom_media" />
                    
                    <if cond="try==2">
                        <audio src="media/sorry.wav" />                        
                        <goto next="#fin" />
                    <else />
                        <assign name="try" expr="try+1" />
                        
                        <clear namelist="msg" />
                        <reprompt />                    
                    </if>
                <elseif cond="msg=='#'" />
                
                    <if cond="rds==true">
                        <audio src="media/au_moins1_chiffre.wav" />
                                
                        <throw event="nomatch" />
                    <else />
                        <goto next="#form2" />
                    </if>
                <else />                
                    <if cond="msg.indexOf('#') != -1">
                        <submit next="#confirm_msg" namelist="msg" />
                    <else />
                        <throw event="nomatch" />
                    </if>
                </if>
            </filled>
            
            <noinput>
                <assign name="try" expr="try+1" />
                <if cond="try==2">
                    <audio src="media/sorry_mais.wav" />    
                    <goto next="#end" />
                <else />
                    <clear namelist="msg" /> 
                    <reprompt />
                </if>                
            </noinput>
            
            <nomatch>
                <assign name="try" expr="try+1" />

                <if cond="essai==3">
                    <audio src="media/sorry.wav" />
                    <goto next="#fin" />
                <else />
                    <clear namelist="msg" /> 
                    <reprompt />
                </if>
            </nomatch>
        </field>
    </form>

It's work perfectly except the key pound.

After I input the dtmf for the message, and press key pound, the time left 20s (interdigittimeout).

I would like to get the filled section immediately after the key pound with this grammar.

The problem is the termchar property?

Can you help me?

Thanks.

Hi,

The reason why you are experiencing this interdigittimeout after entering the pound key is because your IVR grammar includes the "#" key in it. So, this gets affected by your IVR property, interdigittimeout, of 20s.

As mentioned in a previous post, our IVR platform doesn't support the termchar property, as seen here:
http://www.plumvoice.com/docs/dev/voice ... s:termchar

If you want to use the pound key for termination, you may leave the "#" references out of your grammar, as our platform allows you to use the # key for termination by default.

An IVR code example:

digitentry.vxml:

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
  <form>
    <field name="myfield">
      <property name="interdigittimeout" value="20s" /> 
      <grammar type="application/x-jsgf" mode="dtmf">
        ( 1 | 2 )+
      </grammar>
      <prompt>
        Enter any number of the digits one or two.
      </prompt>
      <filled>
        You entered <value expr="myfield"/>.
      </filled>
      <nomatch>
        You did not enter any ones or twos.
        <reprompt/>
      </nomatch>
      <noinput>
        You did not enter anything.
        <reprompt/>
      </noinput>
    </field>
  </form>
</vxml>

If I call into this IVR application and enter "1221#" on my phone keypad, the platform will not wait for the interdigittimeout of 20s because of the pound key termination.
