I almost agree with Todd's points except that when a war dialer identifies
a phone number except for ISP PPP NAS devices, the username password module
may not work as planned since the prompt will be of NAS device or
customized login prompt: if so modified.

In a true PBX environment, most username/password schemes are made up a
voicemail number (last 4 digits of a direct dial number for external
callers and last 3 digits for internal, depending on the phone system ) and
password (usually a combination of numbers ranging from 1 (very bad) to
8(limitation).  On some of the newer phone systems that forward voicemail
to a person's email, (real usernames can be used).

I have yet to find a war dialer that is capable of this type of
username/password grinding.

Toneloc is good for finding modems.  But, the value of the commercial

guessing (read vulnerability testing).

Knowing you have 55 numbers that answer with a tone and knowing that you
have 55 numbers that answer with tone and have easily guessable
username/passwords are two different things.

The comparison in the IP world is running a port scanner and a vulnerability
scanner.  You can either receive a list of xxx number of systems that MIGHT
be running vulnerable services and xxx number of systems that ARE running
vulnerable systems.

If you use a war dialer or port scanner, someone will need to manually test
the target systems to find out if they need attention to fix the
vulnerabilities.

I've used ToneLoc on several occasions, and it's worked perfectly for me.
It's even worked under NT using my pcmcia modem.  Who cares if it hasn't
been updated since 1994?  It tells me what numbers have a tone or not, which
ones have a busy signal, etc... that's all I need for an initial recon of my
client's phone system.  I usually take the list of detected carriers and
compare it to their phone list and see who owns the lines.

My .02c worth.
