A niche feature, but with call recording enabled when the audio file is emailed to you any DTMF presses that the user presses is also included in the email as an XML file. The body of the email also includes the DTMF presses but the XML file includes timestamp details.
eg here is an XML file for a DTMF of '5'
<?xml version="1.0" encoding="UTF-8"?>
<dtmf channel="1" key="5" time="6000" length="240"/>
</dtmf>
You can then process the XML file with your own systems.
This could be useful in the following situations:
*Use the voicemail greeting as a questionnaire - record your voicemail with your questions and explain to the caller to press the buttons on their phone to answer them.
*Track a caller through a IVR route
