In our auto-attendant, we have now provided callers with an option to leave a message containing their name and address details for a product catalog (see Using a Voice Question Action). Those details are recorded as a voicemail message sent to the Sales group's mailbox.
However, by default no message waiting indication is sent for hunt group messages. Instead you must decide who should receive message waiting indication for hunt group messages.
Those who receive message waiting indications do not have to be group members. However, non-members can only access the mailbox and collect messages if the mailbox have the mailboxes access code.
