Can't get simple config working!
...ail(u1002)
exten => 1002,102,Voicemail(b1002)
exten => 1002,103,Hangup
And this is my sip.conf file.
[general]
port = 5060
bindaddr = 0.0.0.0
allow = all
dtmfmode = inband
context = from-sip
[1001]
username = 1001
type = friend
context = from-sip
mailbox = 1001
host = dynamic
secret = liebchen
nat = 0
[1002]
username = 1002
type = friend
context = from-sip
mailbox = 1002
host = dynamic
secret = liebchen
nat = 0
Any ideas?
Thanx,
Mike.

[LLVMdev] Adding diversity for security (and testing)
...ed a "just-in-time code reuse" attack that repeatedly uses a memory disclosure and JITs an attack based on the results [1]. So while it does make the attackers job harder, it doesn't prevent such attacks.

In which release did FLAC support 192kHz sample rate?
...file causes the player to crash, while the 24-bit 96kHz file simply
refuses to play. Hopefully a future firmware update will add support for
24-bit FLAC files.
Note: This article referenced that FLAC 1.1.3 was used.

Difficult sample for vorbis w/ audible artifacts
...is a 9 second clip of the track where the artifact is most
apparent, drone_short.pac is a 1 minute clip of track. The sample is from
the song "Drone" from "Autechre - Peel Session". The longer clip is
compressed with LPAC which can be found here:
http://www-ft.ee.tu-berlin.de/~liebchen/lpac.html
Basically, what happens is when encoding this file at lower bitrates with
vorbis beta 4 there is some very bad pre-echo on the sharp attacks. I have
been told that pre-echo handling is still being worked on though so maybe
there is not much that can be done yet. I was told something ab...

bitrtate peeling and lossless compression
I just read some of the discussion on the list about 'bitrate peeling' and
remembered an interview of Monty that I have read recently. In it he says
that Vorbis uses MCDTs <sp> and that these are theoretically reversable.
And now, I learn that theoretically we can use bitrate peeling to make
smaller files from larger ones, and that leads to my question. Could I

[LLVMdev] Adding diversity for security (and testing)
Greetings LLVM Devs!
I am a PhD student in the Secure Systems and Software Lab at UC
Irvine. We have been working on adding randomness into code generation
to create a diverse population of binaries. This diversity prevents
code-reuse attacks such as return-oriented-programming (ROP) by
denying the attacker information about the exact code layout. ROP has
been used is several high-profile recent
