Outbound Call Delays

[RandyINSite]

We are experiencing excessive delays at the beginning of outbound calls, on the order of 10 to 11 seconds. I suspect this is due to callee_type detection, but I need to know what, if anything, we can do to reduce the delay.

The code I am using is below:

Please note that I removed the finalsilence attribute from the record tag, in an attempt to reduce the delay. This did not help.

Hi,

If this delay only occurs at the beginning of your IVR outbound calls, then it's most likely that the cause for this delay is due to callee type detection.

If you would like callee type detection disabled for your account, please send an e-mail to support@plumvoice.com with your IVR customer ID in the subject line requesting for 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

Greetings.
I have changed my code as follows, with partial success.
I added the prompt block at the beginning.

There is now only a 2 or 3 second delay before playing the first message (the new prompt block).
However, it now seems to always detect the callee_type as answering machine, and hangs up before playing the prompts.

Please tell me where I went wrong.
Thank you.

Hi,

Currently, your IVR code is set up so that it always assigns the variable, "callee_type", with the value "answeringmachine".

You would want to adjust your IVR code to something like this:

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
$calleetype = $_POST['callee_type'];
?>

<vxml version="2.0">
<property name="inputmodes" value="dtmf"/>
<property name="voicename" value="lauren"/>
<form id="mainmenu">

<block>
<prompt>
<voice name="lauren">
<prosody rate="-10%">
Please listen to the following important message from Dr. xxx.
</prosody>
</voice>
</prompt>
</block>

<var name="callee_type" expr="'<?= $calleetype ?>'"/>

From this example, the callee_type would be assigned either the value, "voice", or "answeringmachine".

Hope this helps.

That was the problem, sure enough.

I had to adjust the line you changed to read:

<var name="callee_type" expr="'?= $calleetype ?'"/>

The VoiceXML Validator would not pass the original version:
<var name="callee_type" expr="'<?= $calleetype ?>'"/>

because of the internal brackets.

Thank you for your help with this.
