Plum IVR Support

Under the FAQ, a question is posted as to whether Plum supports HTTPS/SSL. In the response, it says:

"Yes. Please note that the platform will even retrieve pages from HTTPS sites without certificates issued from a certificate authority. If you are having problems retrieving content from an HTTPS site, you can test the page retrieval by using the Netscape (http://www.netscape.com/) or Mozilla (http://www.mozilla.org/) browsers to retrieve the encrypted content."

Does this mean that anyone who knows the URL can retrieve the VoiceXML - with no authentication needed?

HTTPS/SSL is an encryption protocol -- it does not interactively authenticate the user. Thus, anyone who knows the URL for the site will be able to retrieve it. HTTPS/SSL only guarantees that the data passed between a browser and an HTTPS web site will be safe from interception due to encryption. If authentication is required, a second mechanism needs to be put into place like HTTP-Basic authentication which embeds username/password information in the HTTP request header.

For example, anyone can type in https://www.networksolutions.com/. The "lock" icon in your browser should appear indicating that the contents of the web session are now encrypted. However, please notice that you are not prompted for a username and password in order to view the site.

In the same way, the Plum Voice Platform can request VoiceXML content from a web server using HTTPS. This allows for sensitive information to be passed between the IVR Platform and the web server. The web server must provide its own mechanism for authentication if access to the sensitive information needs to be limited to only permitted users.

When Plum tries to access an https site with a self-signed certificate, the following error appears:

Thu 03 Jun 2004 01:00:32 PM EDT (000000;000;1086281939) [inet] ERROR: Error fetching document due to SSL certificate problem, verify that the CA cert is OK

I'm assuming Plum does not recognize self-signed certificates? or is there potentially some other problem?

Can you provide us with a URL to this SSL server with some test vxml? You can email it to support@plumvoice.com or simply post it here on the IVR forum.

Thanks!

Do you maintain a list of supported certificate authorities that Plum accepts. I find I am encountering the following error when attempting to use https in outbound calling:

Attempting to fetch https://x/eva/OMQ/VXMLStartMessageRequest.aspx
Error fetching document due to SSL certificate problem, verify that the CA cert is OK
DocumentParser::FetchBuffer - could not open URL: https://x/eva/OMQ/VXMLStartMessageRequest.aspx
DocumentParser::FetchDocument - exiting with error result 2
errno: 203 uri https://x/eva/OMQ/VXMLStartMessageRequest.aspx

NOTE: I've replaced our domain name with X in the above example.

The certificate we're currently using is issued by: Equifax Secure Inc.

We ran a test on the page with the following sites. Those with a **** had a problem. Our observation was that our certificate seemed reasonable on all of the latest versions of browsers.
