Before you can use the wvrmailbox command, you must import the admin custom server (see Importing application objects) and make sure that it is running (see Blueworx Voice Response for AIX: Managing and Monitoring the System).
wvrapplprof -n -I 123456 -N name -S application -E entrypoint -B 5
wvrmailbox -m -I 123456 -M 6 -F mailbox_status -V 1
To set or modify the options for a mailbox, use the wvrmailbox -m command with the -F and -V flags as described in wvrmailbox command.
