msg_status
Indicates whether the message is new (MSG_STATUS_NEW), saved (MSG_STATUS_SAVED), or outgoing (MSG_STATUS_OUTGOING).
profile_id
Application profile ID of the message sender or receiver.
mailbox_id
A value from 1 to MAX_MAILBOXES that identifies the mailbox that holds the message.
msg_number
The index of the message within the mailbox. If transaction_id is NULL, the value is interpreted as the physical index of the message in the mailbox. Otherwise, the value is used in combination with the transaction_id to identify the message. For example, the first message in a mailbox with a transaction_id=A is identified by msg_number=1. The next message with transaction_id=A is identified by msg_number=2.
transaction_id
Transaction ID. Optional, but if it is supplied, it must match the transaction ID stored in the database with the voice message.
