Chapter 23 Configuring Your Cisco IOS Gateway for T.37 On-Ramp and Off-Ramp Fax Support
Configuring Your Cisco IOS Gateway for T.37 On-Ramp and Off-Ramp Fax Support
Configuration Example
This configuration is an example of a minimal Cisco IOS configuration for Cisco Unity inbound fax
capability. This example includes the configuration of both the On-ramp and Off-ramp applications. The
most important configuration commands are in bold font.
Step 3
fax interface-type fax-mail
Example:
se-10-0-0-0(config)# fax interface-type fax-mail
Configures the gateway to process and forward fax
calls. Also makes T.37 router debugs available.
Note After this command, reload the router.
Step 4
call application voice offramp
flash:app_faxmail_offramp.2.0.1.3.tcl
Example:
se-10-0-0-0(config)# call application voice offramp
flash:app_faxmail_offramp.2.0.1.3.tcl
Specifies where the router can find and read the TcL
script that the gateway needs to process received fax
calls.
Step 5
mta receive maximum recipients number
Example:
se-10-0-0-0(config)# mta receive maximum recipients
10
Specifies the number of simultaneous recipients for
SMTP connections on the gateway to limit the
resource usage of the gateway. The default value is 0,
which causes:
• The gateway to not answer any SMTP requests
• All Off-ramp transactions to immediately fail
Step 6
mta receive aliases string
Example:
se-10-0-0-0(config)# mta receive aliases cue.com
Specifies a valid hostname that will be accepted as a
SMTP alias for off-ramp faxing. The string in this
command can either be an IP address or DNS type
hostname. You can configure multiple aliases
(maximum is 10) in order to accommodate different
domain names and IP addresses.
Note If the destination hostname of the inbound
mail does not exactly match the alias you
configure using this command, all SMTP
connections will fail.
Step 7
mta receive generate permanent-error
Example:
se-10-0-0-0(config)# mta receive generate
permanent-error
Configures the router to flag every DSN message as a
permanent error, so that they are immediately sent
back to the sender (the IP Fax service mailbox),
where the service can determine how many retries
should be attempted, based on user configuration,
when the is a busy signal or no answer. Otherwise, an
error can be flagged as a transient DSN error and
Cisco Exchange trys to resend the message for a very
long time. This command is only in IOS versions
12.3(7)T and later.
Step 8
end
Example:
se-10-0-0-0(config)# end
Returns to privileged EXEC mode.
