This topic describes the functions that can be called from the Vesp_dip external function.
Note:
Any function that can accept an EDUID can also accept a string of the form #channelnum, for example, #17. For more information, see the VOX Server Programmer's Guide.
Return codes
All Vesp_dip functions can return the following values.
Return Code |
Value |
Description |
-100 |
ERROR_NO_VESP |
Avaya Computer Telephony is not available. The VOX Server is not connected to Vesp_dip. May indicate a network error that separates the VOX Server and Vesp_dip. May mean that the VOX Server was not started. |
-101 |
ERROR_BAD_REQUEST |
The command is not known to the Vesp_dip. Probably indicates a misspelled command in the CONVERSANT or Avaya IR application. |
-102 |
ERROR_VESP_EXCEPTION |
Avaya Computer Telephony raised an exception on this request, this is, the request failed. The VOX Server log will have more information. May indicate the passing of an invalid (badly formatted or terminated) EDUID, or an attempt to use a workflow transaction improperly, or an error in a Contact Engine Server's configuration. |
Creating custom variables
Many of the functions described in this topic return information that should be stored in custom variables. For information about how to create a custom variable, see Creating new (custom) variables in the Avaya IVR Designer Help.
Some function attributes require a Dummy variable. A Dummy variable is a custom variable with Length set to 256 and Type set to character. Use this variable only for external function attributes that require a Dummy variable. Do not use the Dummy variable in any other part of the application. You can name the Dummy variable whatever you want. The name Dummy is used here as an example only.
