OMTP VISUAL VOICEMAIL INTERFACE SPECIFICATION v1.2
5. CLOSE NUT INTERFACE DESCRIPTION
If available, the New User Tutorial (NUT) is implemented in the client. It is
usually played the first time the user uses the VVM application if the
subscriber status is “new subscriber” (see STATUS SMS Description (System
Originated)). The VVM service enables the client to disable the New User
Tutorial (NUT) flag in the server via a custom IMAP4 command to change the
provisioning status of the customer in order for the server to avoid re-playing
the TUI NUT. The CLOSE NUT command can be invoked only in the
authenticated state, meaning that the user must be in the authenticated
IMAP4 session.
For details about the command syntax used to change TUI languages, see:
CLOSE NUT Request Syntax (chapter 5.1)
CLOSE NUT Response Syntax (chapter 5.2)
5.1. CLOSE NUT REQUEST SYNTAX
The CLOSE NUT request syntax is as follows:
CNS3 XCLOSE_NUT
In case of invalid command syntax, the following error is returned:
No unknown command
5.2. CLOSE NUT RESPONSE SYNTAX
Upon successful NUT CLOSE, the following response is returned:
CNS3 OK NUT closed
Note: A successful CLOSE NUT command changes the VVM subscriber
provisioning status and triggers a STATUS SMS message (see STATUS SMS
Description (System Originated)).
The following error can also be returned as part of the CLOSE NUT response:
CNS3 NO system error
