User manual

• Set the number of times PhoneSweep will call back numbers that were busy (Busy redial after

calls).

• Activate or disable Sequential dialing of phone numbers (We recommend you do not enable

Sequential dialing, so PhoneSweep will dial numbers randomly)

• Enable or disable Emergency Number (911) Screening and modify the Emergency Number

(911) Screening list (on a per-profile basis). (We recommend you never disable this list).

• Use PhoneSweep in environments where your dialing needs change periodically (for instance, if

you need to dial the same numbers from multiple locations)

4.7.1 Setting dialing prefix and suffix

Any strings specified in these fields will be dialed before and after the phone number in each call

PhoneSweep makes, respectively. The dialing prefix is intended for any access code you need to dial to

reach an outside line, or other information that may change depending on your location. Either the prefix

or the suffix may be appropriate to hold calling card information, but be aware that your modem has a

limit on how many characters it can dial at a time. The maximum number of characters a modem can dial

at a time is generally around 50, but will vary by modem. Consult the documentation for your particular

modem for more information.

There are some modem commands that usually belong in the Dialing Prefix and Dialing Suffix fields

instead of the phone numbers themselves, because it is more difficult to adjust these values dynamically

in the phone number than the Dialing Prefix and Dialing Suffix fields. These include:

• The W or w character (capital or lowercase w) will cause your modem to wait for a second dial

tone. If you are using a system that gives a second dial tone when you dial the code for an outside

line, this pause will ensure that the actual phone number after the prefix will not be dialed

prematurely.

• The comma character (“,”) will force your modem to pause, for most modems, for pause length

defined in the S8 Register. The normal default pause for comma is 2 seconds.

4.7.2 Sequential scanning

By default, PhoneSweep dials numbers in a random order. If you wish PhoneSweep to dial numbers

starting at the lowest number and ending with the highest, select the Sequential check box.

Using sequential scanning in conjunction with Penetrate mode can cause problems. Trying a number

of brute-force username/password combinations on one modem before going on to the next number can

tie the modem up for long enough to interrupt service to other users.

Maximum calls per number per day should not be used in conjunction with sequential scanning. If

PhoneSweep must call numbers in order, and it reaches the allowed number of calls before it is finished

with a number, it will wait. Calls to the remaining numbers in the profile will be postponed until the

earlier numbers can be completed.

4.7.3 Setting PPP mode

PhoneSweep features the ability to identify and brute-force PPP systems. ToneLoc and similar programs

do not have this functionality. A PPP system uses a binary protocol that is not comprehensible to text-

based systems.

PPP mode is only relevant at the Identify and Penetrate levels of effort. PPP bruteforcing uses the same

bruteforce.txt file as normal text-based bruteforcing, but PPP bruteforcing can generally make only one

username/password guess per call.
