Feature Overview

Store and Forward Fax enables Cisco AS5300 access servers to send and receive faxes across

packet-based networks. With Store and Forward Fax, the Cisco AS5300, acting as the on-ramp

gateway, receives faxes from end users and converts them into TIFF ﬁles. It then creates a standard

Multipurpose Internet Mail Extensions (MIME) e-mail message and attaches the TIFF ﬁle to it. The

on-ramp gateway then forwards this “fax-mail” to the messaging infrastructure of a designated

SMTP server, where the fax-mail message is stored. The messaging infrastructure performs message

routing, message storage, and transport, and can be either a standard Internet Mail Transport Agent

(MTA)—for example, UNIX sendmail—or custom store-and forward fax software. The

responsibility of delivering the fax-mail message falls to SMTP and the mail server.

After the fax-mail is stored on the SMTP server, it can be delivered either as an e-mail message with

attachment when the recipient downloads messages or as a standard fax to a Group 3 fax device. In

the latter case, the SMTP server mail delivery infrastructure delivers the fax-mail to the Cisco

AS5300 acting as an off-ramp gateway. The off-ramp router converts the attached TIFF ﬁle back into

standard fax format and then sends the information to a standard Group 3 fax device. The off-ramp

gateway is also responsible for generating delivery status notiﬁcations (DSNs) and message

disposition notiﬁcations (MDNs).
