Re: use OpenBSD to blacklist phone calls?
SUCCESS the package mgetty+sendfax can be used to intercept phone calls by callerID using fax answer after modification to port mgetty+sendfax --- notes --- I had ordered a generic modem for asterisk usage, but was warned that it may need Zaptel support by a subscriber, so that was a wasted $6 + $9 shipping, so I went back to the scrounge pile and found in an old external USR modem that supported callerID, AT#CID=1 After a modem relearning curve I got mgetty+sendfax running Some tips: # grep cua /etc/ttys cua00 /usr/local/sbin/mgettyvt100 on insecure #to pickup changes to /etc/ttys kill -1 1 #And you make config changes and want to make #sure mgetty picks them up you can kill the mgetty PID #and /sbin/init will restart it. HOWever... mgetty from the port package would ignore the configuration file /etc/mgetty+sendfax/dialin.config I discovered the port package needs to also uncomment a line in the default policy.h file the line to use dialin.config. If you look at the used policy.h files you will see /* #define CNDFILE dialin.config */ I found the existing patch that already touches the file, /usr/ports/comms/mgetty+sendfax/patches/patch-policy_h_dist And I edited out the comment on that line and remade the patch, diff -u and saved result over patch-polich_h_dist (also attached to this email) Then I removed the package, and port working directory and make package. IT WORKS now. I'll send an email to port maintainer about it. If someone see how this becomes a security issue to enable, please inform. ... So in conclusion I implemented this on OPENBSD 4.0, and if you want to use the callerID feature mgetty+sendfax... http://home.leo.org/~doering/mgetty/mgetty_15.html#SEC15 You will have to recompile after modifying policy.h I added none for UNKNOWN callerids and some recent pesty callerIDs and the !all at end of the dialin.config file and its so sweet to have the fax answer the telemarketers. It looks like mgetty.config has hooks and could use external resources to phonenumbers to block, so some of the jokes about using something like spamd-setup may be feasible :) but for now I can edit /etc/mgetty+sendfax/dialin.config and mgetty reads the text file changes w/o hangup signal or restarting the process.

Re: use OpenBSD to blacklist phone calls?
mgetty might have something useful - see http://home.leo.org/~doering/mgetty/mgetty_15.html thanks. Hmm, maybe it can be as simple as setting up fax support for just the black list. From what I read on your link, it suggests the configuration can be set to only accept for specified numbers. That way the listed phone numbers for telemarkers could get a fax response which can be really annoying. The next step may be to send any fax responses to /dev/null I just ordered a Wildcard X100P card for $5.95 through googlebase and started the build for /usr/ports/comms/mgetty+sendfax Maybe late next week I can try this approach and report back.

use zapteller() [ page 115 ] and / or anti-girlfriend-logic [ page 104 ] as documented in the Asterisk - the future of Telephony.

[EMAIL PROTECTED] (now renamed trixbox) is a CentOS-based linux
distribution with pre-installed Asterisk and supporting pieces.
I'll take the opportunity to point out that {3.9,4.0}-stable
ports trees have just had an update to Asterisk to fix a remote
(unauthenticated user) chan_sip vulnerability (-current has
had 1.2.16 since shortly after unlock). Packages later.

Sam Fourman Jr. Some phone companies have a service where you need a four digit code to complete the call. My friend has this, after the first ring you here a recording that says something like, this number is currently unavailable or something to that effect. If you punch in the special code you connect pass this. I think it's a few dollars a month and you can setup a white list so some numbers don't need the code.
