CVP VXML Server 4.02

ICM 7.2.3

Comprehensive Call Flow


I deployed a test application from VXML Studio, the app simple plays an audio.

When I invoke the application from the ICM Script, it plays :

"I'm sorry, there was a problem with this application. Please call back later. Thank you."

The log in the CVP Server says:

Oct 31 2008 10:41:11.203 -0300: %CVP_4_0_IVR-3-CALL_ERROR: CALLGUID=770CC403-A69311DD-8909BADF-12D5E68D DNIS=91994 CVP VXML Server encountered a No Session error - URL: (Client: [id:3023]

30: Oct 31 2008 10:41:11.203 -0300: %CVP_4_0_IVR-3-CALL_ERROR: RunScript Error from [CVP_NO_SESSION_ERROR(44)] CALLGUID: 770CC403-A69311DD-8909BADF-12D5E68D DNIS=91994 {VRUScriptName: 'GS,Server,V' ConfigParam: ''} [id:3023]

Who has to give to the CVP VXML Server the Session ID parameter?

thank you in advance

Hey rolecram1960,

I faced the same problem. The error causing this was because of wrong URL defined in ICM Script. Correct one is:



So in ICM Script Editor config goes like this;

Set Variable Media Server = "http://VXMLIPAddress:7000/CVP"

Set variable Media Library = ".."

Set Variable ToExternalVXML = "application=HelloWorldFromICM"
