When you are just getting started, the item that you almost certainly need to define in the configuration database is the phone number that is used to call into a CCXML document or a specific application. This is specified on the NodeName entry, like this:
NodeName=VRNode1
NodeDefLocale=en_US
VRNode=yes
NumToApp=123455,name
;
where name is the name of a VoiceXML application, a Java application, or a CCXML service.
When you write one of your own applications, you must either run it from a CCXML document or add a number-to-application mapping for it either by using the dtjit configuration tool as described in Updating the configuration database, or by editing the default.cff file, and then run dtjconf, to import the new definitions into the configuration database.
When a call is routed to the Java environment, the called number is used to look up the appropriate action, using the NumToApp mapping. See Mapping a VoiceXML or Java application to a phone number and Mapping CCXML browsers to a phone number for details.
