MailboxExists() Conditionally branches if the specified voicemail box exists
MailboxExists(mailbox[@context[,options]])

Checks to see if the mailbox specified by the mailbox argument exists in the Asterisk
voicemail system. You may pass a voicemail context if the mailbox is not in the
default voicemail context.
This application sets a channel variable named VMBOXEXISTSSTATUS. If the mailbox exists,
it will be set to SUCCESS. Otherwise, it will be set to FAILED.
If the j option is passed as the options parameter, the application will jump to priority n
+101 (where n is the current priority) if the voicemail box specified by the mailbox
argument exists.
