Figure 1 shows a simple network topology using Store and Forward Fax.

Figure 1 Topology Showing Store and Forward Fax Functionality

Store and Forward Fax functionality is facilitated through Simple Mail Transfer Protocol (SMTP).

Additional functionality is provided in this product to provide conﬁrmed delivery using existing

SMTP mechanisms (such as ESMTP) for those features.

In Store and Forward Fax, you can collect accounting information about fax services in two ways:

• Using RADIUS accounting. (For more information about using RADIUS to generate accounting

data, see Cisco IOS Release 12.0(4)XJ Store and Forward Fax.)

• Collecting the accounting information using SMTP

The ESMTP Accounting in Store and Forward Fax feature enables you to collect accounting

information about fax services as part of the SMTP session. This functionality is activated through

the use of an intelligent fax client or MTA. In ESMTP accounting, the off-ramp gateway (acting in

its capacity as an ESMTP server) advertises capabilities to the MTA, which is acting as an e-mail

client. One of the capabilities the off-ramp gateway advertises is xaccounting, which means that it

supports ESMTP accounting. If the MTA recognizes the xaccounting service extension, the MTA

(acting as the client) can accept the ESMTP accounting information sent from the off-ramp gateway.

If the MTA does not recognize the xaccounting service extension, it will not send the xact command

to the off-ramp gateway. In that case, the off-ramp gateway will not respond with ESMTP accounting

data.
