Figure 7-4. Sending an outgo ing IP fax to a fax machine
Following is an example of an IP fax configuration that enables the MAX unit to handle
outgoing fax calls as shown in Figure 7-4:
Ethernet
Mod Config
IP Fax Options
IP Fax Enabled=Yes
Login=ipfax
Password=works
With this configuration, the MAX unit processes an IP fax as follows:
1The fax server on the local network receives fax data across the Internet from a remote fax
server.
2The fax server initiates a connection to the MAX unit, sending its login name and
password in the first TCP packet.
3If the login name and password match the Server-Login and Server-Password values,
respectively, in the IP-Fax profile, the MAX unit establishes a TCP session with the fax
server. If authentication fails, the connection is cleared.
4After authentication, the MAX transfers control of an available modem to the fax server.
5The fax server sends modem commands encapsulated in TCP packets, initiates a
connection to the destination fax machine, and sends the spooled data. If no send or
receive activity occurs for more than 2 minutes, the session is terminated and resources are
freed.
Note: For fax accounting, a fax session starts when a modem resource is allocated and stops
when a session is terminated.
Fax hangup codes and disconnect cause codes
Conexant supplies two fax hangup codes:
•+FHNG 1—when fax tones are recognized but the handshake fails
