Plum IVR Support

Unfortunately, I have not been able to get curl to output any error messages. However, there is a facility in php for supressing error messages. You can place any offending IVR code inside a <block> as follows: $name = "/some/nonexistant/file"; ob_start(); // creates a catchall buffer $fd = fopen($n...

There is no built in facility in VoiceXML for accomplishing this for recorded audio. There is a way that you can achieve this by implementing this at the IVR server side instead. Generally, you'll need to: 1. create an IVR script that can take two arguments - the file to be played and the time offse...

You'll need to do this in post processing on the IVR server. Fortunately, with headerless 8 bit u-law pcm files, appending is as simple as concatenating files. Then the concatenated audio file can be played back to the user as a single file. Before you get back to your IVR application server, you ca...

The simplest structure is for the ASP to directly return VXML on the IVR platform.

Here's an IVR example of an array returned from a <subdialog> : <?xml version="1.0" encoding="UTF-8"?> <vxml version="2.0"> <form id="caller"> <block> <prompt>Going to jump.</prompt> </block> <subdialog name="subd" src="#callee"> <param name="myid" expr="'caller form'"/> </subdialog> <block> <prompt...

When submitting, the document being submitted to must return a valid voice XML document. Assume the following <submit> statement is used: <submit next="http://www.myhost.com/upload.php" method="post" namelist="final_recording"/> This would be an invalid page for upload.php: <?php foreach ($_FILES as...

The two most common reasons an error.semantic is thrown are: 1. The VXML document is malformed. 2. Invalid ECMAScript is executed. The first case cannot be caught. Since VXML is based on XML it is unable to do analysis of the IVR code if it is malformed, and so cannot react to IVR errors in the VXML...

When using <param> to pass a value to a subdialog, you must redeclare the variable name in the subdialog script you are using. Example: Calling Page: <?xml version="1.0"?> <vxml version="2.0"> <var name="local_parm1" expr="'A B C D'"/> <var name="local_parm2" expr="'1 2 3 4'"/> <form> <subdialog src...

There are several different timeout parameters that can be set as attributes of the PROMPT tag or as property values. For voice input or DTMF input, the <prompt> tag attribute timeout determines the time until a NOINPUT event is thrown. The following are IVR properties that can be set at a field, fo...

If by "flash support" you mean using the Flash Communication Server as an IVR application server in conjunction with ECMAScript and VoiceXML, then, yes, the Plum Voice Platform can work with any IVR application server. It may be that you will need to modify your server side IVR code to return result...

The IVR error "error.sematic" usually refers to a parse error in the document. Have you tried to use the validator for the page you are trying to go to? Or better yet, just try pointing the vxml platform to that page directly. I suspect that the vxml being generated by the "../global/log_call.vxml" ...

It is unclear what you mean by using flash with voice XML; please give a specific IVR example of something you are trying to accomplish given the 2 technologies. Here are some other bits of information you may find relevant to your question: Macromedia Flash is a visual interface; It is primarily us...

- Is it possible to adjust the quality of the audio file being recorded? Currently, the IVR system does not provide a built-in method for adjusting the quality of the audio as it is rendered to the caller. The upcoming IVR platform release will support multiple encoding types for the <record> tag (...
