Looking at the VoiceXML returned by that link (http://www.voicexl.com/VoiceXLPlumPortals.vxml) there appears to be some extra characters in your initial IVR form:

Code: Select all

<?xml version="1.0" ?>
<vxml version="2.0">
 <form> 
 Â  <block> 
 Â  Â  <goto next="http://www.voicexl.com/VoiceXLPlumPortals.vxml" maxage="0"/> 
 Â  Â  <goto next="http://www.voicexl.com/VoiceXLPlumPortals.js" maxage="0"/> 
 Â  </block> 
 </form> 

You may want to retype this form by hand. If it is not showing up in your web browser you may want to try a different one.

Hope this helps

OK - I retyped by hand and do not see any extra characters.
Can you look? I still get content errors

You do not appear to have disabled caching, you have added a <block> at the beginning of your VoiceXML script that would clear the cache if it were in its own document or a scratchpad prior to this fetch, but instead the Plum IVR platform is still fetching this document (for it's initial fetch) from the cache. I have cleared the cache using my own scratchpad, but you now have the problem that the block at the beginning of your document creates an infinite loop (essentially going to itself over and over again).

To resolve these IVR issues, you need to first remove the initial form from that VoiceXML document, and from the Plum IVR Hosting interface create a new scratchpad that contains that form. Save the scratchpad and set the DNIS of your account to that scratchpad and then call back into the IVR system.

Hope This Helps

That helped, thanks.

Can you tell me the preferred audio format for the Plum Platform?

wav/vox, 8khz etc ?

[support]

8Khz 16-bit linear mono PCM is the preferred audio format for the Plum IVR Platform.
