Yes, you read right. This phone recorder will record up to 22 hours of telephone messages or conversation. It will automatically advance itself to the next numbered message after phone is hung up (Mode B, there must be approx. a 10 second pause between phone calls). This allows every phone call to be labeled separately within a message folder. There are 4 message folders, A, B, C, D. Each folder is able to hold 99 messages.
When in "Mode B", each recorded message is numbered separately. When a message folder fills up to capacity (99 messages), simply advance it to the next message folder (B, C, or D). Phones calls are time-date stamped when viewing on computer with included software.
When recording in "Mode A" phone calls are not separated within a message folder.
