Plum IVR Support

It seems like it takes forever until I here the first recorded prompt. How can I make sure most of my members I'm calling don't hang up because of the dead air in the beginning?

Here is my script:

<?xml version="1.0" ?>
<vxml version="2.0">
<form id="main">
<record finalsilence="1000ms">
<noinput>
<goto nextitem="myprompt"/>
</noinput>
</record>
<field name="myprompt" type="digits">
<property name="termtimeout" value="700ms"/>
<property name="timeout" value="700ms"/>
<property name="inputmodes" value="dtmf" />
<grammar type="application/x-jsgf" mode="dtmf">(0|1|2|3|4|5|6|7|8|9|"#"|"*")</grammar>
<prompt><audio src="http://audio.plumgroup.com/root/5224840 ... o></prompt>
<filled>
<goto next="#PERSON"/>
</filled>
<noinput>
<goto next="#VOICEMAIL"/>
</noinput>
</field>
</form>
<form id="PERSON">
<property name="inputmodes" value="dtmf" />
<field name="menuchoice">
<grammar type="application/x-jsgf" mode="dtmf">(1)</grammar>
<prompt><audio src="http://audio.plumgroup.com/root/5224840 ... o></prompt>
<filled>
<if cond="menuchoice==1">
<goto next="#TRANSCARD"/>
</if>
</filled>
<noinput>
<goto next="#CMS"/>
</noinput>
<nomatch>
<goto next="#TRANSCARD"/>
</nomatch>
</field>
</form>
<form id="VOICEMAIL">
<block>
<prompt bargein="false"><audio src="http://audio.plumgroup.com/root/5224840 ... o></prompt>

Hi,

About this delay that you are experiencing, it is a result of the IVR's callee type detection trying to determine if you are a "voice" or an "answeringmachine" when you pickup an IVR outbound call.

We can disable IVR call type detection for you if you would like. If so, please send an e-mail to support@plumvoice.com with your customer ID in the subject line requesting for IVR callee type detection to be disabled. The customer ID would be found in your support contract with Plum. If you do not yet have a support contract with Plum, you should contact your sales representative regarding this IVR issue.

Regards,
Plum Support
