Configuring IP fax options
Example of an IP fax configuration for incoming faxes
Figure 7-3 shows a MAX unit receiving an incoming fax across the PSTN. The unit then
initiates a TCP session with a fax server, which authenticates the incoming call. (The fax
server might use RADIUS, as shown in Figure 7-3, or a method proprietary to that server.) If
the fax server authenticates the call successfully, it dials out to the remote fax server on one of
the MAX unit’s modems. When the fax transmission is completed, the fax server terminates
the TCP session and the MAX unit regains control of its modem.
Figure 7-3. Receiving and forwarding incoming IP faxes
All Calls Are Fax Enable/disable the handling of all incoming calls as IP fax
calls. When this parameter is set to no (the default), the MAX
unit recognizes incoming fax calls by matching the caller’s
DNIS number to one of the Fax-DNIS numbers specified by
DNIS #N [N=1-4]. With the yes setting, IP fax service can be
supported where DNIS is not available.
DNIS #N [N=1–4] Up to 4 DNIS numbers. The MAX unit compares the DNIS
number supplied in the PRI setup message of an incoming call
to the configured numbers. If the match is not exact, the unit
does not start the IP fax function.
Servers #N [N=1–5] IP address of one of up to five fax servers. The fax server sys-
tems are typically on the local IP network, but local connec-
tivity is not a requirement.
The MAX unit first tries to connect to the fax server at the
first specified address. If the unit receives no response, it tries
to connect to the second address. If the unit still receives no
response, it tries the third, and so forth. Once the MAX unit
connects to a fax server successfully, it continues to use that
address for subsequent connections until a connection attempt
fails, at which point it tries the next configured address.
