You can receive an incoming fax using any of the following methods:
Receive and forward to email: The Messaging system acts like a fax server and hence you do not need a third-party fax server. If the recipient user belongs to a Class of Service (CoS) that allows fax, the user receives the fax in the inbox of the configured e-mail address.
Detect and transfer to fax server: If the recipient user belongs to a CoS that allows fax, the user receives the fax through the user fax server account.
The maximum transmission length for an incoming fax is 90 minutes. However, if the fax transmission exceeds the 90-minutes limit, the fax messages are handled gracefully, that is, the fax transmission is stopped. The fax message to the user contains the pages sent in the first 90 minutes of the transmission, and the sending fax machine is notified of the number of pages sent successfully.
