Saving Money With Analog Calls
By default, the I-modem anticipates the rare occasion that telephone company
equipment incorrectly allows a digital connection when you call a modem or
fax machine. In these situations, although the I-modem proceeds with the call
as a standard analog (fax or modem) call, the telephone company bills the call
as digital.
Digital and Analog Billing Structures
Often the billing structure for digital (“data”) calls is different than for analog
(“3.1 kHz audio”) calls. In some areas, telephone companies charge a flat rate
for analog local calls and bill digital calls by usage at a metered rate. Although
all long-distance calls are typically metered, long-distance digital calls tend to
be slightly more expensive than long-distance analog calls.
To do this
Use this setting
Prevent the I-modem from behaving like a
fax/modem over digital connections

When you use this setting, and the I-modem detects an analog device over a
digital connection, it ends the call. If you check the call status information by
sending I6 , the I-modem reports:
Disconnect Reason is Analog Destination Over a Digital
Network Connection.
Forcing Analog Calls
If your calls to analog devices fail and you can’t figure out why, you can always

To do this
Use this setting
Force analog calls (and be billed at analog rates)
