The getvdu function retrieves a single value from the call's EDU. For example, a customer's account information can be looked up in the database and stored in an EDU on the EDU Server. The EDU Server passes the requested information to the VOX Server, which in turn passes the value to the VRU. This function also updates the name/value pair stored in the VOX Server's value cache. For information about getvdu and the value cache, see the VOX Server Programmer's Guide.
Note:
Always issue the getvdu function instead of getvox if there is any risk of other software running in parallel with your CONVERSANT or Avaya IR application; otherwise, pertinent EDU values may differ.
