B.131. VMAuthenticate()

Authenticates the caller using the voicemail password of the specified mailbox.
Behaves just like Authenticate() except that the passwords are taken from the configuration (and optional context) in voicemail.conf.
If a mailbox is specified, only the password for that mailbox will be accepted. If it is not provided, any voicemail password will be accepted! The channel variable ${AUTH_MAILBOX} is then populated with the name of the authenticated mailbox.
Option s suppresses the prompt.
; use the dialed extension as the reference mailbox and authenticate:
exten => 123,1,VMAuthenticate(${EXTEN}@sales)
exten => 123,n,SayDigits(${AUTH_MAILBOX})
