Do you have any suggestions for a true dtmf only mode input?
You need to use the
<property> tag to set the
inputmodes to dtmf in those areas of your IVR code where you want to only allow dtmf input.
<vxml>
<!-- only dtmf input will work in this document now... -->
<property name="inputmodes" value="dtmf" />
<form id="myform">
<field name="myfield">
<grammar type="application/x-jsgf" mode="dtmf">
[0][0](1|2|3|4|5|6|7|8|9|0|"#"|"*")
</grammar>
<prompt>Please enter something. This prompt cannot be interrupted by background noise... only dtmf input.
</prompt>
</field>
<filled>
<!-- evaluate and go about your business... -->
</filled>
</form>
<form id="myform2">
<!-- ...except in the scope of this form, where we have -->
<!-- explicity alllowed voice as well -->
<property name="inputmodes" value="dtmf voice" />
<field name="myfield2">
<grammar mode="dtmf">1|2</grammar>
<grammar mode="voice">yes|no</grammar>
<prompt> Say yes or press 1. Or say no or press 2. Extraneous noise could barge in on this prompt if loud enough... Get a quieter office?
</prompt>
</field>
<filled>
<!-- evaluate and go about your business... -->

Hope this helps,
