There are three possible PPP identification/brute-forcing settings:
• Normal PPP: In this mode, if PhoneSweep attempts to identify a text protocol and fails, it will
see if the remote device will respond to PPP protocol packets.
• Never use PPP: In this mode, PhoneSweep will not send PPP packets to attempt to identify a
system that it cannot identify with text protocols.
• PPP only (no text): In this mode, PhoneSweep will only identify and brute-force systems which
respond to PPP protocols.
4.7.4 Emergency Number (911) screening
Emergency Number (911) screening is a measure to prevent PhoneSweep from calling emergency
numbers such as 911. PhoneSweep's Emergency Number (911) screening is enabled by default, and it is
strongly recommended that it be left enabled in North American environments.
The Emergency Number (911) screen list defaults to 911 and 9911. However, these may not be the only
numbers that connects to emergency services in your area. You should be aware of local emergency
numbers in your area, and add them to the Emergency Number (911) screening list, and avoid including
them in profiles. NOTE: The Emergency Number (911) screening operates only on a per-profile
basis. For every new Profile you create, you must change the Emergency Number (911) screening
list.
Sandstorm does not warrant that 911 screening will prevent all calls to emergency services.
• To disable 911 screening, click on the check box to deselect it.
• To add numbers to the Emergency Number (911) screening list, click on Add, type the
number(s) into the dialog box that appears, and click OK. Multiple numbers may be added,
separated by a comma or space.
• To delete numbers from the Emergency Number (911) screening list, highlight the number
you want to delete, and click on Del.
4.7.5 Redialing busy numbers
The Busy Redial field sets the number of times that PhoneSweep will redial a busy number before giving
up on it. A number that is always busy should be investigated further, since it may be a modem that was
in use every time PhoneSweep attempted to connect to it. (Default value is 5 calls.)
4.7.6 Setting modem baud rate
The Modem Baud Rate setting can be changed to accommodate the maximum speed at which your
modems will attempt to connect. For maximum reliability, we recommend connecting at a 9600 bps
(baud). Higher baud rates do not significantly improve PhoneSweep's calling throughput, and may reduce
reliability on some combinations of PC, serial I/O interface and operating systems. Many PBX systems
are unable to handle high baud rates as well, especially older systems.
4.7.7 Setting Single Call Detect (SCD) mode
Normally, you should leave SCD mode enabled (Use Single Call Detect if available, normal dialing if
not). The default attempts to use SCD on any call that is placed in both carrier mode and fax mode. We
recommend that use this default setting. The other settings available are:
o Always use Single Call Detect triggers a modem error if PhoneSweep attempts to use SCD and
fails. (We recommend you do not use this setting)
