String CallIvr(ByVal phoneno As String, ByVal appname As String, ByVal selfdelete As Boolean)

Parameters

phoneno - The phone number to call.
appname - The name of the deployed IVR application.
selfdelete - Ask the gateway to automatically delete the call request after the call is made if it is set to '1'.

Returns

Dim reqId As string = CallIvr("123-4567", "reminderApp", 1)

String CallStatus(ByVal reqId As String, ByRef responses As)

Check the call status of the call with <reqId>. If the call is made, the return value is 'Call Made', or if the call is failed, the return value is 'Call Failed', or if the call will retry, the return value is "Call will Retry", and for any other status, the return value is " " (empty string).
