[asterisk-users] Voicemail Forwarding

[--[ UxBoD ]--]

Experiencing a problem when users attempt to forward a voicemail from within VoiceMailMain(Option 8) I see the console message:

Couldn't not find mailbox XXX in context default

As why are running in a multi-tenant environment voicemail.conf has been separated into individual contexts.  The users retrieve their email by dialing an extension which calls VoiceMailMail(XXX at VMContext) so how do I instruct Asterisk to use that context when forwarding voicemails ?
