Figure 7-4. Sending an outgoing 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:
1 The fax server on the local network receives fax data across the Internet from a remote fax
server.
2 The fax server initiates a connection to the MAX unit, sending its login name and
password in the first TCP packet.
3 If 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.
4 After authentication, the MAX transfers control of an available modem to the fax server.
5 The 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
