 I see MANY of these in my log files:

 What is the correct way to block these idiots so they
 don't even get this far.

 Thanks,

At this past year's AstriCon there was a series of security talks that
covered fail2ban and best practices. You can view the playlist of videos on
YouTube. The content should be helpful for you:

Links to the playlists are also on asterisk.org:

Re: [asterisk-users] how to install asterisk in ubuntu?

2014-01-15 Thread Billy Chia 
There is a step-by-step tutorial with video on the Digium blog:
http://blogs.digium.com/2012/11/14/how-to-install-asterisk-11-on-ubuntu-12-4-lts/

Additionally Emiliano's advice is excellent

You can read Asterisk - The future of telephony and get a lot of stuff.

 Emiliano.


However, I would recommend you read Asterisk the Definitive Guide. The
Future of Telephony is now an outdated version of the book and the name has
been changed to the Definitive Guide. In the modern version of the book
there is installation instruction for both redhat-based and debian-based
linux.

Re: [asterisk-users] How do I remotely force an *unconfigured* Digium DPMA

2013-09-09 Thread Billy Chia 

 Apparently notify.check-sync does work but only if you're NOT using
 the DPMA. I just tried it and the phone just responds with a 200/OK
 and does nothing.

Did you disable enable_check_sync in the xml config?

By default this option is enabled and phones should restart with
check-sync SIP NOTIFY
